If I understand your question correctly, you're seeking to determine if
new.ontime is "in the past". If so, compare with current_timestamp /
current_date as appropriate, eg:
IF new.ontime IS NOT NULL AND new.ontime < current_timestamp THEN
(Note that current_timestamp and current_date are constant within a
transaction, so they might not be suitable if you have really long
running transactions).
