I'm writing a custom trigger function that has to compare values of
time* types and make some actions depending on a result.
Answering my own question, Alvaro proposed a solution with
extract(epoch from tz_value), the result is in seconds:
postgres=# select extract(epoch from '00:00:00+0'::timetz) -
extract(epoch from '2:00:00+2'::timetz);
?column?
