RE: "Does anybody really know what time it is?"

Hi Jonathan,

> What is a GMT epoch second?

Here's what I plan to do to answer this:

1) Take a vacation to England.
2) Go to Greenwich.
3) Find a Linux box.
4) $ date +%s

   1015000988
5) "Meditate" on this while continuing vacation and exploring other time zones.

Right now the best data that I have on time is...

What is a GMT epoch second? This curious mind wants to know.

I can get UTC time by:

alter session set time_zone='00:00';
select current_timestamp from dual;

But this doesn't get Steve the epoch seconds that he wants.

Oddly enough, with all this new time zone functionality, I don't see any way to easily translate a TIMESTAMP WITH TIMEZONE value from one time zone to another. For example, if I have 2-Feb-2002 10:30:00.00 PM -05:00, how would I go about converting that to Pacific Time (-07:00)? It seems like there ought to be a function to do it for me (NEW_TIME won't work here), but the solution doesn't appear that easy.

Best regards,
