Hello
I am working on trunc and round function now. I have some problems with
timestemp with time zone datatype. First question?
is correct behaviour (I am in GMT+2 time zone)?
select current_timestamp, date_trunc('year', current_timestamp),
date_trunc('month', current_timestamp);
timestamptz|date_trunc|date_trunc
"2005-07-31 10:46:39.087+02"|"2005-01-01 00:00:00+01"|"2005-07-01
00:00:00+02"
I expected for all values time zone + 2.
Next questions. Is correct idea?
trunc(timestamptz '20010101 10:10:10+8', 'IYYY') --> 20010102 00:00:00+8 ??
or 20010101 18:00:00+02 (24-6) or 20010101 19:00:00+01 or ???
There are somewhere some rules about behavior timestamp with time zone?
Thenk You
Pavel Stehule
