Could you trace through the timestamp conversion routines and determine
exactly what's going wrong? The problem is most likely in or near
DetermineLocalTimeZone() in src/backend/utils/adt/datetime.c. We've
heard some reports of misbehavior of the C library's mktime() routine
on certain platforms, when given a time near a DST boundary in certain
timezones (what timezone do you use, anyway?). DetermineLocalTimeZone
attempts to defend itself against this, but perhaps is not completely
successful. Unfortunately, none of the developers have a machine on
which mktime() misbehaves, so it's hard for us to figure out much more
about the issue...
