Nokia Lumia :: 800 Doesn't Keep Time?

The clock of my Lumia 800 runs too fast, in a week or two, it will be 3-4 minutes ahead of time, and in a month it's already 5 minutes, this is just unacceptable. The difference gain slows down with time so to keep it within a minute I need to set the time very often (weekly).

I've tried using manual time, and automatic, both of which don't help the problem, and it seems the automatic time option doesn't even work since no matter what time you set, when you switch it to automatic, it doesn't do anything. To be honest, I'm a little disappointed by the support this phone has gotten since it's release, especially with the firmware updates.
