Re: epoch from date field

Actually, we use tzset() to set the timezone.  We're not operating in GMT
at all, but it returns GMT.

This, however does work returning the epoch for the current timezone:

select extract(epoch from map_date::timestamp);

So, for some reason extract won't convert a date to timestamp when it's
passed in?

Thanks for the help,
