Re: Trouble with UNIX TimeStamps

Sorry, I'm still to new with using functions within PostGreSQL, but . . .
I've tried:

SELECT to_char((1040999196 || ' seconds')::interval +
ticket_starters.ticket_time_start::timestamptz,'Day') FROM ticket_starters;

and it returned back:

ERROR: Cannot cast type integer to timestamp with time zone

So constructed antoher query:

SELECT to_char((1040999196 || ' seconds')::interval +
ticket_starters.ticket_time_start::timestamp ,'Day') FROM ticket_starters;

and it returned back:

ERROR: Cannot cast type integer to timestamp without time zone

In my table, the column, ticket_time_start has a INTEGER value of
'1009462540' which is today's date.

How'd would I construct the query to pull from the db?

One way to do this is:
area=> select to_char('epoch'::timestamp + (1040999196 || '
seconds')::interval,'Day');
to_char
-----------
Friday
(1 row)
