coming from samsung stock 4.2.2 I patched my device with autopatcher for obtaining root and flashed cwm 184.108.40.206.
I tried several roms, but I have a strange issue.
After rebooting my device it is showing a random timestamp and a random date. Restarting it several times I have dates in November, January, etc.
Timesync is only functional via ntp (internet time sync).
I tried different custom roms (cm 10.2, cm 11, aosp 4.3). Always the same behaviour.
I had this issue before but suddenly it went away but I didn't know what I have done.
But after installing my device new the problem stays - regardless which custom rom. I admit I have not tried the stock rom again.
I currently made a new backup in twrp. The timestamp of the backup is ok. (I rebooted from cm 10.2.1 directly to recovery). But after boot the timestamp correct timetamp is gone.
