Hi George,
Difference of two timestamps directly :
dbtest=# select 'now'::timestamp - '2000-12-06 13:47:57+00'::timestamp
as "Time Interval";
Time Interval
---------------
02:49:34
(1 row)
Number of seconds converted to hh:mm:ss :
dbtest=# select '12345 seconds'::interval as "Time Interval";
Time Interval
---------------
03:25:45
(1 row)
Hope this helps
Francis Solomon

Subject: [GENERAL] MySQL-esque sec_to_time() function
Hello,
I'm converting from MySQL to PostgreSQL (actually flipping/flopping
back) and have a question:
MySQL has a cool function sec_to_time() which converts your number of
seconds to hh:mm:ss
I've read thru the mailing lists and am basically trying to implement
the following:
MySQL:
select sec_to_time(sum(unix_timestamp(enddate) -
unix_timestamp(startdate))) from foo;
PostgreSQL:
select XXX(sum(date_part('epoch',enddate) -
date_part('epoch',startdate))) from foo;
I just need to know what XXX is/can be. I've tried a lot of
combinations of the documented functions and come up with useless
conversions.
Thanks,
George Johnson

PS: i can't find documentation on how to load the functions in contrib.
I can compile and
install them O.K., but not sure how to make them load.
