I'm very sorry to hear that you are experiencing that date and time are reset when you restart your device. This will be fixed in an upcoming software release. I'm sorry for any inconvenience this causes until then.
UPDATE: The roll out for software version 39.2.A.0.386 have now begun. Please note that timings and availability may vary by country and/or carrier

Does your phone has a taskiller or antivirus? does it has a SIM card?

I have the same problem with Android 7.0 on my Sony Xperia XZ.
Nougat version: 39.2.A.0.327
With Android 6.01 I could switch the smartphone off and on again without the clock was reset.
Since I have carried out the update on nougat, the clock is reset when I turn the smartphone off and on.
Is there a way to fix the problem.

PS. The safe mode I have not yet tested.
Also, I have not reset the smartphone to factory settings.

Same issue. Clock resets to some date in March and WhatsApp says there's an invalid date. Only when the phone syncs to cellular network time, then everything is corrected. WTH Sony!
