NLog LogEventInfo TimeStamp should default to DateTime.UtcNow #5899
Description
It is annoying that one must always remember to specify correct NLog Time-Source to get accurate timings:
<time type="AccurateUtc" />https://github.com/NLog/NLog/wiki/Time-Source
Instead NLog should change so it uses AccurateUtc by default, but support changing timestamp-output to be local-time (default) or utc-time (explicit). Similar to being able to change the default-culture on LoggingConfiguration / LogFactory, then it should be possible to change the default-time-zone (default local)
The overhead of converting from UTC-time to Local-time should only apply to targets that requests Local-time output using ${date} / ${longdate} / ${time} / etc.

Looks like NET11 (and newer) will improve the granularity of the Environment.TickCount on Windows, so it will match Linux/MacOS and update every 1ms instead of every 16ms:
