Sansa e200v2 clock drifting

[siber_cat314]

I'm not entirely sure if this is a hardware issue or a software issue, but a while back I updated the firmware on my e200v2 player, and ever since then the clock hasn't kept correct time. It didn't bother me too much, but when my dad complained about something (can't remember what) on his old version of rockbox on his player, I updated his as well and now his clock is drifting as well. I've since returned to my Gigabeat f10, but for the sake of pinning down this bug, I've just installed r29302 on mine.

Any idea what's going on?
