Windows Phone Thoughts: Did Your Pocket PC Adjust For Daylight Saving Time?

I have 6 active devices right now and two didn't adjust themselves for Daylight Saving Time this morning, a WM2003 iPAQ 2215 (ROM 1.1) and a WM2003 iPAQ 3900. My Jornada 565 (2002), Axim X5 (2002), iPAQ 3600 (WM2003 - yes, that isn't a typo) and EM500 (2000) all adjusted fine. Since the 3600 did with Microsoft's build of 2003 on it, it leads me to think there is something in the iPAQ/HP builds, or somehow I told them not to autoadjust, though I can't find where to set that setting on my Pocket PC.
