[Android Central Question]

Take battery out of my phone and the screen will have Dec 31st at 7:00 am. Then about 30 sec later it will show the correct time and date. Why?????

Which phone ?
Once you turn off the phone and restart it, it searches cell towers and probably be little delay until time is correct.

Welcome to Android Central! You're taking the battery out and putting it back in? Why are you taking the battery out in the first place?

And how is the phone running without a battery?

You don't say which year, but 1969-12-31 would be the Unix date of zero (1970-01-01) adjusted for a western (negative) time zone.

The correction that happens after that would be the phone getting the correct time and date from the cellular system it is connected to.

If you are seeing this "zero" date in the first place, it would seem to suggest that your motherboard does not have a correctly functioning battery to maintain the internal clock, etc, while the main battery is temporarily removed.
