It's a hacked Philips 7000/17 S2 box (apparently running 4.0.1b-02-2-240), so I can't apply DirecTV's software update. Any idea how to fix this? There is no zoneinfo directory on the Tivo file system, so I don't know where its DST rules live. The clock is correct w.r.t. GMT, it just doesn't know what the new DST rules are.
I don't understand why this didn't happen last year. I think I would have noticed.
* It stopped recording The Daily Show at the proper time because I use a "manual" recording for that one (to stop getting a dozen copies of it a day when Comedy Central botches the metadata, which is often).
