why is the automatic time and date option not available on my samsung galaxy 3 tablet?

[AC Question]

Sometimes the time and date on my tablet is not always accurate and i would like to know why the feature to the automatic time and date is not available on this tablet?

If there's no phone in the tablet there won't be an automatic time/date. (It gets the time and date from the phone tower - if it has a phone in it.)
