I am running Windows 7 and Ubuntu 17.04 Zesty version in a dual boot configuration. The problem I am facing is this: - The system clock shown in the two OS remains different (separated by 5 hours and 30 minutes).
I am actually in the Time Zone of south Asia (GMT+5:30). For example, if in Windows OS,I set the time as 00:00, as soon as I reboot the system and open Ubuntu,the system clock in Ubuntu starts to show 5:30. Similarly, setting 00:00 in Ubuntu OS shows +5:30 in Windows and so on. This happens for whatever time I set in any of the OS. The other OS starts to show the time that is +5:30 ahead.
