Well, it would be nice to have a timestamp version so that users didn't
have to keep typing "extract(epoch from timestamp)"... but yeah, I
suspect that would work fine for timestamps. For intervals I suspect you
could just convert to seconds (if we're going to add timestamps, it
seems like we should add intervals as well).
