For now While stuck with your unfortunate solution: CHECK ((end_time AT TIME ZONE 'UTC' AT TIME ZONE 'US/Eastern')::time = '23:59:59'::time) That's right, AT TIME ZONE two times: The first instance transforms your timestamp without time zone into timestamp with time zone. that's assuming you are actually storing UTC times. The second instance converts ...
You may use to_char to get the time fields from a single function call: check (to_char(end_time at time zone 'UTC' at time zone 'US/Eastern','HH24:MI:SS') = '23:59:59') Seconds given by SS are not rounded up so that should be OK as an equivalent to floor
Try this. It maybe be faster, but still unreadable: alter table bananas add constraint ck_end_time_is_end_of_day check ( (end_time at time zone 'UTC' at time zone 'US/Eastern')::timestamp::date + interval '23:59:59' = date_trunc('second', end_time at time zone 'UTC' at time zone 'US/Eastern') ) ;
