Consider adding this information more explicitly (rather than just showing via the examples).

There is some of amount of configurability of the time zone and precision of timestamps via the LOG_FORMAT and LOG_FORMAT_FILE configs. Here's a brief summary:

Log format	Time zone	Aware vs. naive	Precision
text	UTC	naive timestamp	second
debug	system local time zone	naive timestamp	microsecond
json	UTC	aware timestamp	microsecond

There's some more nitty-gritty code details discussed here.
