An App for exact time with Live Tile or a mode to reset watch.

[WPCentral Question]

The auto setted time on my Ativ S is a little screwed up. It's 5-6 minutes wrong compared with atomic exact time watches on internet.
I've tried to set manually, but I can't decide, see or reset seconds. So, for example, if when I set the new time, the seconds are 55, then after 5 seconds I have +1 minute.
Is there a way to completely reset watch or at least decide the second counter? Or an App with a Live Tile?
