Time Synchronization
Time synchronization done using NTP Server.

The actual time is defined by the revolutions of the earth around the sun.
if you know your time, and the location of the sun, you can figure out your position exactly. Use that for navigation.
The difficulty with time synchronization is that a bunch of regions work in different timezones. Just think Daylight savings time.
