Then there must be some issues with time.
It can be problem in that my country use UTC+1:00 but GPS send data in UTC time? I don't understand why traccar count time only from rows with alarm information but from other not.
Probably late on this : )
But set tracker TK103 Time zone via config file or sms:
Does your device report hours?
