Which units are used for peekTime, totalTime, etc...?

Is it milliseconds, microseconds, something else?

e.g. 

```
Query: insert into foobar values ( 1, 2 );

200 OK
commitCount: 3
lastInsertRowID: 1
nodeName: DESKTOP-DIFRTR1
peekTime: 296
processTime: 58
totalTime: 3664
unaccountedTime: 146
Content-Length: 0
```
