How to format bigint field into a date in Postgresql?

Question

I have a table with a field of type bigint. This field store a timestamp. I want to date format the field like this :

to_char( bigint_field,\'DD/MM/YYYY HH24:MI:SS         


        

Answer 1

This depends on what the bigint value represents - offset of epoch time, or not.

select to_timestamp(20120822193532::text, 'YYYYMMDDHH24MISS')

returns

"2012-08-22 19:35:32+00"
