I have Dell Axim V50v and have same problem.
I sync at home to Windows Vista PC that has automatically updated itself to correct new daylight savings time here in US.
I also sync at work on Windows 2000 PC that is locked as large corp. It has also been updated for correct time.
But my Axim has wrong old - time. When I correct time on Axim manually to correct time, it gets "corrected-overidden" when sync to old time.
I think it's correcting to a GMT plus x hours to my time zone but the two PC's are on Daylight savings but my Axim is not and thus the reason it's overriding it. I think I need to set my Axim to daylight savings but I haven't found a way to do this.
Help please . . .
Update - looks like pach for pur pocket PC's is also available as discussed in different thread at:
