I saw the 10:30 time on a TV advertisement, so I'd say it's pretty reliable.Maybe there's a rerun or retrospective at 10:00.
The E! website says 10:30 p.m., but all the TV listings services say 10:00 p.m.Set your DVRs accordingly.
Actually, now the web site says 10:00, and a "Married to Jonas" episode at 10:30.
