First there is no indication of what DATE1 and DATETIMEZOZE1 are, so the result you show has no context.
Second why are you doing all this? You are taking a timestamp (I presume) converting it to a string and then converting it back to a timestamp, just to to timestamp subtraction.
From what I can piece together you seem to be wanting to get the interval between two timestamps, is this correct?
Is so or if not, show us a schematic representation of what you are trying to achieve. For example:
'07/13/2015 07:03:15'::timestamp - '01/01/2015 14:15:00'::timestamp = interval in days, hours, etc
Inline image 1 But in oracle using systimestamp,to_timestamptz and SS TZH is not supporting to_timestamp in postgres. result.. Inline image 2 diffrence is days displaying in postgres query..i thnk something wrong. is it..? any help apprictiated.

Forget my previous post, Rays post made me realize the error of my ways, namely thinking current_timestamp-to_timestamp was a function. -- Adrian Klaver adrian.klaver@xxxxxxxxxxx <mailto:adrian.klaver@xxxxxxxxxxx>
