I whipped up a BlackBerry application that syncs the device time to a network time source every 12 hours. It isn't a true NTP client, but better than nothing. Anyone interested in the application? If so I can share. In return you can let me know if you find any bugs.

Theoretically it will run on 3.6 and higher devices, but I only tested as far back as 4.2. In 5.0, the device automatically does this. Lots of folks have complained about the time skew (attributing it to missing meetings) and having to manually update the time. Since there are still a ton of legacy devices out there I figured I would toss the idea out.
