Re: Postgre 7.3.x Bug with datetime formatting.

Hi,

There is a problem with the to_char function when it formats the timestamp;
in the example below; The HH is different between both calls.

select current_timestamp, to_char(current_timestamp, 'YYYY-MM-DD
HH:MM:SS:US')

returns

timestamptz to_char

--------------------------
--------------------------

2004-05-05 13:25:12.332313 2004-05-05 12:05:12:332313

Regards,

Safwan

Looks fine to me. I suspect what you are wanting is HH24:MI:SS, not
HH:MM:SS.

I did realize my mistake regarding the time. But the hours is still wrong.
Here is the call as per change. The result still shows a variation.

-----
select current_timestamp, to_char(current_timestamp, 'YYYY-MM-DD
HH24:MI:SS')

timestamptz to_char
-------------------------- -------------------
2004-05-07 08:59:24.713109 2004-05-07 07:59:24

I'm new to Postgre; is it possible to set the timezone or clock of Postgre
different from local machine; I didn't setup the machines; but if you tell
me how to get you the settings for postgre, as well as the local or timezone
settings for the machine, we might be able to figure out the discrepancy.
As you see in the result above, the hours is still incorrect.

Regards,
Safwan

Hm, that is odd. What timezone are you running under? (The output of
SHOW TIMEZONE would be interesting.) Also, exactly which Postgres
version is this, and on what platform?
