The forum will experience an outage sometime between February 10 at 7:00pm EST and February 12 at 11:59 EST for installation of security updates. The actual time and duration of the outage are unknown but attempts will be made to minimize the downtime. We apologize for any inconvenience.

We host database for some online applications and some of our new customers are located in another timezone.

Since we have all database running in just one box, is that possible to configure timezone in database/db server, this way sa will not use OS timezone.

What version are you using?

AFAIK, v12 has introduced the new data type TIMESTAMP WITH TIME ZONE and the new special value CURRENT UTC TIMESTAMP exactly for such use cases.

Actually it's all in 11. We are planning to upgrade to 12 this year.

FYI, DEFAULT UTC TIMESTAMP and CURRENT UTC TIMESTAMP have been around since version 8, but before version 12 their type was TIMESTAMP.

Now I'm somewhat puzzled what exactly has been improved with v12:

  • Does v8+ (and the "time_zone_adjustment" option) allow a client to adjust the display of UTC time values to the local timezone (i.e. it allows to correct between displayed and stored times? (But one should still store UTC times in case different time zones do matter, e.g. with the help of DEFAULT/CURRENT UTC TIMESTAMP.)

  • Whereas the v12 TIMESTAMP WITH TIME ZONE type allows the storage of times with local time zone information, so clients do not need to adjust the display, and the time can still be stored in a standardized way?

Before version 12, one always needed to know what timezone was used for values in timestamp columns. All that DEFAULT/CURRENT UTC TIMESTAMP provided were ways to get UTC timestamps instead of the timestamps in the local server OS timezone provided by DEFAULT/CURRENT TIMESTAMP.
