6785 RETROTV guide data seems to be off by one hour

I recorded 6785 RETROTV on TVE via Comcast Kirkland (WA) at 5PM and at 5:30PM. The programs were listed as Doctor Who S16E15 and Doctor Who S16E16, but what was actually recorded was a program shown in the guide to be on at 6PM, Republic of Doyle.

Apparently this is a known issue with RETROTV, so I wonder if there's any way to shift the guide data for that one channel by one hour?

See previous posts, same issue with other Get After It Media channels
