Обсуждение: Timezone conversion

Hi,
How can I do timezone conversions in PG? I looked on the docs and
couldn't find how. I want to find the current time in another timezone.
Thanks,
-Roberto

P.S: This type of function would be excellent on the cookbook
(www.brasileiro.net).

Umm.. define 'it'.  (Isn't current_timestamp or now() already a
timestamp?)

select CURRENT_TIMESTAMP, CURRENT_TIMESTAMP-2*3600;      timestamp        |  ?column?  
------------------------+------------2001-04-24 13:06:11+03 | 1981-08-07

I also have a question.. How, for example, would I add 90 days to the
current timestamp?

Thanks,
-Cedar

Hi Cedar,

Does this help?

select CURRENT_TIMESTAMP, CURRENT_TIMESTAMP + '90 days';
      timestamp        |        ?column?        
------------------------+------------------------2001-04-24 12:57:56+01 | 2001-07-23 12:57:56+01
