Is there anyone who knows the answer as to why now() is delivering a
different
time answer than Windows?

Before I asked this question yesterday, I had already checked SHOW ALL and
found only two PostgreSQL config parameters that seemed to apply, and they
appeared to be set properly:
australian_timezones = no
TimeZone = US/Eastern
We are running 8.0.1, Windows 2003.
Since last message, checked 3 other servers, and found that I have the same
problem on two out of three:
Server #1: select now() agreed with Windows time on this one
Server #2: select now() was exactly one hour greater than Windows time
where config parms were set the same as previous paragraph
Server #3: select now() was exactly one hour greater than Windows time,
but config parm was set wrong: TimeZone = Europe/Dublin (don't
know how that happened; makes you wonder if TimeZone has
anything to do with this at all!)
Windows 2003 time was set correctly in all four cases.
Summary:
- one server displays time correctly
- two servers APPEAR to be set correctly, but time displayed from now() as
one hour greater than Windows time
- one server is set incorrectly, but TimeZone did not appear to have any
effect on the time being displayed; now() just displayed time as one
hour greater than Windows time
Being as one server is 'doing it right', there must be some difference, but
so far I have not found what is different. Windows appeared to be correct in
all cases, but PostgreSQL did not.
