Thanks Andreas, I've ended up using CAST( ... AS TIME). I think the :: notation
might be fragile in this instance because of the machine-generated SQL which
gets a bit hairy in places.
I've also had to replace INTERVAL() with CAST( ... INTERVAL) wherever it occurs
and replace the result of a function with TIMESTAMP WITH TIME ZONE... hopefully
that won't mess anything up, the server is aggresively GMT since we have to deal
with several timezones simultaneously and it's the only way I could work it.
