I was careful not to describe it as a perfect solution. (:

I agree that it can be confusing. The rule we try to enforce
is that all internal reporting should be done in UTC time.
Presentation to operators can be done in Local time. Thus,
the majority of the code should not care what timezone its
running in, and always use UTC.

In any event, reading logs where local time is used can be
quite confusing around the time of DST change. If UTC is
used, at least you get continuity in the log.
