Here's a handy little tool to help you keep your phones time in sync. If your carrier doesn't keep the correct time zones on their towers like mine, and you don't sync with your desktop all that much, you might want to give this app a go. The only drawback is that it's only available in German. However, the free price tag should make up for it.
Edited to reflect that it's actually a NTP client and not a NNTP client.
