Sorry, I've obviously misunderstood. Are you just looking to discard the
timezone so they look the same?
select date_trunc('month', CAST(CURRENT_TIMESTAMP AS timestamp without time
zone)); date_trunc
---------------------2002-11-01 00:00:00
I'd have thought that would give you some problems around local/utc midnight
on the first of the month.
Or is it that you want to know what time it was in UTC zone at the start of
the month local time?
If I'm still being a bit slow (quite likely) can you explain what you're using
this for?
