Time is the same everywhere but displayed in different ways according to
local time-zones. In order to deal with non-synchronized clients or
server-side specific values like differentiating between CURRENT_TIME
which returns the time at start of transaction throughout the life of
the transaction and timeofday() which _does_ change throughout a
transaction you should use "SET TIMEZONE". For example my server is on
the West Coast but I can display time for East Coasters:


steve=# show timezone;
  TimeZone
-----------
  localtime

steve=# select current_time;
        timetz
--------------------
  11:06:14.745969-07

steve=# set timezone to 'est5edt';
SET
steve=# show timezone;
  TimeZone
----------
  EST5EDT

steve=# select current_time;
        timetz
--------------------
  14:06:29.456009-04

Cheers,
