I don't have time to test this, or fix parentheses errors on my CASE
statement, etc., but how about something like:

(CASE WHEN TO_CHAR(SYSDATE+(1/48),'HH24') BETWEEN '01' AND '12' THEN
(TRUNC(SYSDATE)+(25/48))
ELSE (TRUNC(SYSDATE -(1/24))+(49/48)) END)

So if the current time is between 00:30:00 and 12:29:59, then the job
runs at 12:30 in the afternoon today,
else if the current time is not between 00:30:00 and 12:29:59, then
the job runs at 12:30 at night (same day if current time is between
00:00:00 and 00:29:59, next day if current time is between 12:30:00
and 23:59:59)

Hope this helps -- Tim
