This is for the same of portability. ecb90a9 Reduce the number of TimeZones.LoadZonesConcurrently threads (from 256 to 128) for portability reasons. a59b930 Merge pull request r-dbi#54 from Sarcasm/master 03db026 CMake: use target_compile_features(... cxx_std_11) when available 41f2ef8 FindGMock.cmake: put GMOCK_LIBRARY as first argument after DEFAULT_MSG b28cf20 Revert "CMake: add CMake "workspace" project to build cctz and its dependencies" 4d6cb4a CMake: changes after review from @Sydius 793f632 CMake: add CMake "workspace" project to build cctz and its dependencies 79c7c0a CMake: remove install target 0225120 CMake: specify C++ standard per-target f6b2a6a CMake: remove -fcolor-diagnostics Ninja workaround 03f1327 add CMake support 4f9776a Avoid weak vtables (see clang's -Wweak-vtables) by making the destructors of TimeZoneIf and ZoneInfoSource "key" functions. 9715eea Add 2017c zoneinfo files to CCTZ for possible use on systems that don't have their own (like Windows). They are also useful for hermetic testing. f1776e9 Suppress testing of %c in FormatParse.RoundTrip on Windows. 47f500e Merge pull request r-dbi#59 from google/fix-benchmarks 9549437 formatted build content b8e502b Fixed GoogleBenchmarks build to work on Windows 15d0cc7 Merge pull request r-dbi#58 from dcower/patch-1 4cd2f98 Fix ambiguous conditional expression via Clang+Windows 3441e33 Tag the time_tool target as "manual". It currently is not portable due to its use of <getopt.h>. bc83a60 Fix problem with strptime() emulation when the entire input is consumed. Add internal support for %% parsing/formatting and %e parsing. Expect %x to match either M/D/Y or D/M/Y. 9e7f637 Merge pull request r-dbi#55 from kant/patch-1 b339a31 Minor fixes (proposal) 12025d6 Define _CRT_SECURE_NO_WARNINGS in the same way as you would get from -D_CRT_SECURE_NO_WARNINGS on the command line (i.e., as 1), the goal being to avoid a redefinition warning. 52564b2 Add a user-defined default constructor for cctz::time_zone instead of using the compiler-generated one and in-class initialization. This avoids a (somewhat bogus) "default initialization of an object of const type without a user-provided default constructor" error when declaring a (somewhat useless, but tested for) const cctz::time_zone. 90bf1bd Change the MakeTime.SysSecondsLimits test case to use fixed-offset zones for far-east/west conversions. Pacific/Apia and America/Dawson both have transitions before time_t(-2147483648) that are not represented in the macOS zoneinfo files, so conversions in the distant past will give unexpected results when using that data. Fixed zones sidestep the issue. d5e227e Merge pull request r-dbi#51 from mwinterb/vs2017-codegen-fix 809b420 Declaring kDigits static to avoid a codegen bug in VS2017. 149b299 Removed incorrect slash after 5b17020 Moves includes into a "cctz" subdirectory. 0e2dd88 Change "BaseTime" to "CCTZ" in benchmark names. f2bdef9 Merge pull request r-dbi#50 from gennadiycivil/master 8f71aaa Switch to googletest provided bazel build files bd0f906 Fixed some compilation issues on windwos 2e86a77 Merge pull request r-dbi#48 from sheu-google/master 416ce79 Fix extern declaration of default_factory with initializer 0a5cc50 Optimize cctz::get_weekday(), cctz::get_yearday(), and civil_time construction with "day" values in the previous year (-365 < d <= 0). Also add a temporary optimization for converting contemporary times in fixed-offset zones. 237c335 Parameterize the BM_Format_{Format,Parse}Time benchmarks by the format string. This will provide better insight into performance changes. Also delete the redundant BM_Format_RoundTrip* benchmarks. c7675c3 Add a new TimeZoneInfo::LocalTime() overload that takes the prevailing Transition. This means we need only perform a single addition in the civil_second domain during an absolute lookup(). 1912dee Remove some trailing white space from lines in README.md. e27a6f1 Fix the civil_time.h link in README.md. ff4b7ae Add benchmarks for civil_time.h interfaces. b6ac6bf BUILD changes that should have been part of the last commit. 2de157c Add benchmarks for time_zone.h interfaces. 75f1f88 added testonly attribute to benchmarks binary 7da4b9f Moved benchmarks to their own file/target 8422279 Adds support for benchmarking e563641 Allow a small number of failures in TimeZones.LoadZonesConcurrently to account for skew between the contents of kTimeZoneNames and the zoneinfo data source. 94c76d4 Add "zdump" support to time_tool. a72d644 cctz::time_zone::lookup(const time_point<D>&) should floor its argument rather than truncate it. The "zero" time_point has no special significance. a5478b9 Add mangled symbol names for _MSC_VER/_M_IX86. f7e17e7 Correct the Windows weak-symbol names. 05f52fe Add support for user-supplied sources of zoneinfo data. 5e7c694 Tidy up some more #include lines. 65554a3 Don't ignore an empty ${TZ} in local_time_zone() and just allow "${TZDIR}/" to fallback to UTC, which will match "env TZ= date". 7c9a405 Tidy up some #include lines. 45e6c87 Fix the dependencies of a couple of examples, the includes of a couple of tests, and some recently added, overly long lines. 669b9d3 Merge pull request r-dbi#45 from gabeschine/master 7185fc7 Guard get_offset_abbr() impls in src/time_zone_libc.cc 8d4b2a5 Move the handling of "localtime" (which typically maps to /etc/localtime) to local_time_zone(), where ${TZ} was already handled. This means that load_time_zone("localtime", &zone) will only look for ${TZDIR}/localtime. 58b8886 Avoid the non-portable %F and %T format specifiers in the examples. 8775f88 Simplify the wrapping of strerror_r(). ecee594 reserves space for format's result string ac5c51a Tweak the new cctz::fixed_time_zone() to take a duration instead of a raw count of seconds. 3daf163 removes accidental blank line 2c89026 Added overflow checking to parse() 65e40c9 Avoid std:: qualifying snprintf() for the time being. 1fa607b Remove TAB character that slipped in during previous commit. 2d4e939 Add support for time zones that are fixed offsets (<=24h) from UTC. b9c7ea8 The 2017b tzdata release moved the shift from -004430 to +00 from 1972-05-01 to 1972-01-07, so we temporarily accept both outcomes until 2017b is ubiquitous. 3db86d4 Define the behavior of cctz::time_zone::lookup(const civil_second&) when the argument civil_second is beyond the representable range of the time_point<sys_seconds> results. The results will be saturated. 10c1855 Parse a civil-time argument with respect to the flag-specified time zone, not UTC. This makes a difference when we are at the extremes of the representable range. 15d4a35 Update test case TimeZoneEdgeCase.AfricaMonrovia for tzdata 2017b. 5759ba5 Now that we have in-class initializers for TimeZoneInfo::local_time_hint_ and time_local_hint_, we don't need any dynamic initialization. 1f928b3 Remove remnant references to DateTime. 52f18a0 Change the civil-time index into the transitions vector from the 64-bit DateTime to a cctz::civil_second. This allows us to reach the extremities of 64-bit timestamps in all time zones. 8306990 Inline the civil-time relational operators. 68d8e15 Merge pull request r-dbi#41 from proller/patch-1 7461a4b Added an error out-param to detail::parse() 5c02ff3 fix valgrind/s Conditional jump or move depends on uninitialised value(s) b7662bc Don't call UTCImpl(), which might initialize a function-local static, while holding time_zone_mutex. This avoids a deadlock on a platform that shall go nameless. 27cbf5a Change cctz::time_zone::absolute_lookup::abbr from a std::string to a const char*. This is an interface change, but it allows cctz::time_zone::lookup(time_point) to guarantee that it does no memory allocations. 38174cf Refactored platform #ifdefs to use sfinae to be a bit more robust a3e0f5c Avoid using a global civil_second (at least until it can be constexpr). 24d310d Stop comparing zone abbreviations until tzdata changes settle down. 6e29f90 Make the n_sec() normalization optimization a little clearer. cce7cec Update tzfile.h to 2017a release. 598e92c Added header guard to civil_time_detail.h d3fc80b Avoid any possibility of a signed/unsigned comparison warning. Also fix an issue should int_fastXX_t be larger then XX bits. 3f70134 Removed now unneeded includes 5572fa3 added section separator 6a11c32 Moved civil-time output streaming to src/civil_time_detail.cc 1338f4d Stop assuming that a zoneinfo file with a future rule will end with two transitions in the same calendar year ... this will no longer be true in the upcoming tzdata release. 79ddaf6 addes OFFSET()/ABBR() defines for myriad2 processors fca4cd4 Made the errnum->string logic more robust 6c7526b Fix cut-and-paste error in previous commit. 71b4c06 Avoid INT*_{MIN,MAX} for portability reasons. 248892d Add explicit but safe narrowing/sign casts to silence -Wconversion. 86f216a Removed linkopt for libm, which is no longer needed 8ad10a0 Stopped linking against pthread, because I don't see why it's needed and it breaks on some platforms 70f46f0 Add ANDROID conditionals for strerror_r() and tm_{gmtoff,zone}. 6b0c187 Add __FreeBSD__ conditionals for strerror_r and tm_gmtoff/zone. Thanks to Rainer Hurling. 9f1f739 Use TimeZoneInfo::Load()::bp (in an assert) before it dies in order to quash a "Value stored to 'bp' is never read" warning from the clang static analyzer. Thanks to Siesh1oo. a856308 Prepare for an upcoming change to third_party/tz/tzfile.h. a3294e3 Optimize civil_time (non-constexpr) construction when the fields are already normalized. 90ef68b Some requested changes to the Makefile. 44d0052 Comment out recently added zones from time_zone_lookup_test in deference to slightly out-of-date zoneinfo installations. 2c5612c Support parsing year values beyond the width of tm_year. cce8c5b Ensure that there are always transitions in the first and second half of the time line so that the signed difference between a DateTime and the DateTime of its previous transition is always representable, without overflow and without (for now) extended precision. bc607f6 Eliminate the possibility of intermediate overflow when calculating civil_time differences. Add test cases that would have previously produced over/underflow even though the final result was representable. c54f233 Fix a problem with Decode32() when std::int_fast32_t is wider than 32 bits. c318823 Eliminate a gratuitous difference between internal and external. 26449a6 Resolve TODO regarding overflow in (civil_day - civil_day). 1f0b1f0 Trim redundant transitions instead of just skipping over them when looking for extension transition types. This avoids a problem when the first future-specification transition occurs before the (y2038_boundary - 1) transition added to workaround Qt bug 53071. a914620 Tweak type of default_transition_type_, and a couple of comments. 0d2b3a9 Avoid fixed-sized typedefs. b2b2f7a Add time_zone::name() and support for time_zone equality. 1e943a3 Use the int_fastN_t types for PosixTransition. Size is secondary. 6e09ceb Increase the resolution of the internal format/parse functions. 04278e7 Sub-nanoseconds are useless when converting to time_point<nanoseconds>. These were remnants of the original implementation. 748f94e Deleted the CCTZ v1 API 6cbb3ef Don't complain if a zoneinfo file does not contain a future rule. 6a694a4 Convert TimeInfo usage to time_zone::civil_lookup. 026a56c Avoid possible integer overflow by adding the UTC offset in the civil_second domain. f8f9996 Rename "tp" to "sec" within parse(). 05cc592 Guarantee that time_point<sys_seconds>::rep is at least 64 bits. Also add a TODO about parsing large year values. 60d37ed Convert Breakdown usage to time_zone::absolute_lookup now that the later supports 64-bit years. bd0df01 Start using civil_time in the time_zone implementation. 66a06c4 Expand civil_time to cover the full range of a 64-bit time_t. cde4bae Remove some now-unnecessary year narrowing. Also pass civil_second by reference to time_zone::Impl::MakeTimeInfo(). 837fb19 Move to 64-bit years in civil_time. This allows, for example, a civil_second to represent all the values covered by a 64-bit time_t. 7e3af34 Avoid overflow on civil_month(<max-year>, 12). c2775b8 Avoid -t flag to install. Add Linux shared-library example. 7d49f0f Add SHARED_LDFLAGS for CCTZ_SHARED_LIB linking. 5362a83 Use install instead of mkdir/cp. Remove shared-library versioning. Make install_shared_lib an independent target. 2e83ff2 A little Makefile cleanup. 5c54e2a Merge pull request r-dbi#30 from vcatechnology/shared-library-makefile 120694c int64_t -> std::int64_t. 5e37bb9 Add a new install_shared_lib target fac30f9 Added the libcctz.so target to the Makefile 5a97215 Support DESTDIR in Makefile 3cde909 Mention the test, tools, and examples object files explicitly so they are created separately and so the generated dependencies are correct. 4b7a168 When extending the compiled transitions using the POSIX-style future rule, search for the last two distinct transition types rather than assuming that the last two transitions already have distinct types. 9fb6bcb Use function-local static initialization instead of std::call_once(). Change time_zone_map to an unordered_map, and which does not include the UTC zone. 4b7f674 Update tests for new-style abbreviations (e.g., +05). a9cefbe adds a license directive to the BUILD file 50745f6 Disallows difference between differently aligned civil-time types e887dac Use _MSC_VER to detect Windows compilation environments. 6bff566 Also use tm_{gmtoff,zone} under linux/__USE_MISC. 72d74a7 Updates to the "install" rule. - Make "sudo" optional. - Try to make the destination directories. - Rework so that the sources are VPATH expanded. 03a14dc Remove weekday and yearday from cctz::Breakdown. These are now exposed as functions on cctz::civil_day. 635f4fe Add %E*f and %E#f support to cctz::format() and parse(). These specifiers deal with only the subsecond part of the time. For a non-zero subsecond, "%E*S" == "%S.%E*f". Like the "ES" formats, # behaves exactly like * on input. d32d4e3 Add some casts during safe narrowing conversions. 61415a0 Fix some issues with the Windows build. b3610cc Linkified some file paths. git-subtree-dir: src/cctz git-subtree-split: 00fc77b843504f231f89c13eff86327c444094e8

Steps:
Updated from google/cctz: 00fc77b843504f231f89c13eff86327c444094e8
Removed .github and testdata directories.
Modified cctz Makefile:
From:
To:
Ported the odbc specific changes made to previous vendored cctz back in and added clear formatted notes in cctz included sources.
Address issue with cctz + odbc + snowflake driver on windows when using arg timezone and timezone_out.
Reported error from windows: Final transitions not in same year.
I would test more before merging.
Then update NEWS / Maintenance
Seems like it was on the todo list. (#568)
