One idea for handling the round-to-localtime issue from the other end of the
problem: optionally rotate logs upon an *interpolated* filename change.
Then, 'server_log.%a' would cause a rotation when strftime() thinks it's
midnight local, 'server_log.%H' would rotate at the top of the hour, etc.
Possibly a half-baked idea.
I also noticed pg_tm.tm_gmtoff is apparently not set, at least not for my
local (US MT).
