Please help: Nexus 4 date & time problem.

Hey guys,

So for the past month or so I've noticed the time on my Nexus 4 is continuously slow. I've tried manually setting it. A day later it's off by a half hour. Setting it to automatic network date & time it's still of by 10 minutes. I have absolutely no idea what would cause this, and really need a fix asap. It's my schedule, alarm clock, and watch.

Thanks for your help and ideas.
