Samsung Galaxy Tab 4 Wifi - Time and date wrong, no automatic setting

[chipnanna]

My android Galaxy tab 4, updated, always showed correct time and date until recently. I manually set it, but afterwards the day changed to a day ahead. It's a wifi only tablet, never has been connected to a cellular account, no cellular chip. I installed and ran Malewarebytes, nothing was found. And in Settings, there is no 'automatic' option. This has never happened before with any of my other Android devices, I have 3 tablets and 2 phones.

This creates problems with my appointments in my calendar, notifucations, etc. I have researched this, and found that a lot of other android users have this problem, but have never found a solution.

Any ideas?

After it went a day ahead, and you put it back to the correct date, has it done it again?
