Different Clocks
Ok this has been bugging me for a while. My phone clock is two minutes ahead of my work laptop and TV. I thought they would all have the same time?

That's super weird. Every device on the internet can make use of Network Time Protocol (NTP) to tsync up its internal clock to within 10 or 20 milliseconds of the international time standards. The software that puts up a display may lag by a few video frames, but that error should be barely noticeable.
Do you have some special app that puts up a time display, or is the display built into the phone's system software?

@ElwoodBlues It's in the phone, it's a Samsung. Me too I thought they all dial into some atomic clock.

@JimboSaturn They should all dial into an NTP server that's 1 or 2 hops away from an atomic clock.
Presumably the GPS in the phone has its own internal clock, but to give you 50 feet of positional accuracy the internal GPS clock has to be within 50 nanoseconds of official GPS time. 1 foot per nanosec, so that internal GPS clock has to be synced mighty accurately.
At least it's good to know you identified the problem. You can probably download some NTP clock app from the play store.
