Re: converting interval to timestamp

If the number of seconds between timestamps is acceptable then this is the
solution I use:

SELECT ABS(EXTRACT(EPOCH FROM t.field1) - EXTRACT(EPOCH FROM t.field2)) AS
diff FROM table AS t;

Adjust to your column and WHERE needs. One caveat: this only works for dates
within the UNIX epoch ( after 1969-12-31).
