Try converting to your database's time format (or date) and then just add the values. The SQL functions for date/time are still pretty much database specific.

What database are you using?

Cheers,

In Oracle you should be able to use something like:

SELECT SUM( TO_DATE( hoursfield, 'HH24:MI,SS')) AS tot_hrs;

Cheers,
