I guess what you're saying is, if TVGoS is active in your area, once you enter a valid zip code for your area, it saves info from these 'timezonepkt's, and once that happens, there are only two ways to change that saved info:
1. Factory defaults reset
2. Move the Pal to another area with TVGoS active, enter a valid zip code for that area, and receive a 'timezonepkt' from that area's TVGoS host station.
... with method 1 being the only way to
erase saved 'timezonepkt' info. Method 2 is even more of a PITA than method 1 anyhow (not to mention becoming less and less practical as TVGoS goes away in more and more markets).
It's far too late to test now, but I wonder what would've happened if I'd left the zip code alone in the used Pal I bought. Presumably, I wouldn't have gotten any guide data from TVGoS because the original owner's zip code wasn't valid for DFW, but I wonder if it would have locked the clock anyway, because his saved 'timezonepkt' info was still there (I never did a factory defaults reset on that Pal)?
Unless part of the info it saves is the TVGoS host channel. If so, that might have stopped the clock from locking onto KTVT (assuming the original owner's TVGoS host was on a different channel) until a valid DFW zip code was entered.
