I think that perhaps I should have Hijack detect accesses to /etc/localtime, and automatically redirect those back to the correct zoneinfo file, based on the path traversal info from the 4 bytes of the flash savearea. Once this is working, timezone info should be automatic for programs that use the standard time functions, outside of the kernel.

That would be a *really* sweet hack.

BTW, I figured out why I wasn't seeing the flash savearea change when I looked at it earlier... I didn't have a /usr/share/zoneinfo directory, because I use my own /usr partition and don't let the player overwrite it. So if you don't have anything there, the player has a default list of time zones, but when you select one, there are no subdirectory entries to point to, hence no change in the flash.
