To Tom Lane, 








- PostgreSQL 7.3.4

- the box is linux. I'm not sure which version or how to find out.  I'm
using my host's server.

To Tom Lane( when I replied to you, your mail server  gave error return
address was refused.)


Here is my response to your email of Friday May, 07.



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



timestamptz                 to_char

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.

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

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




timestamptz                                          to_char
