Time setting anomaly with dual boot


In my Lenovo IP 110 80T70015IH which has Windows 7 and Ubuntu 16.04 in dual boot, the time zone setting was adjusted to local (India) at the time of installing each separately. However they are offset by a few hours -- something to do with the basic machine hardware I guess!
I seldom use Windows, so I ignore the difference, but if I reset in Windows the setting in Linux gets altered.
The only irritant is that a file created/saved in Windows (jpg, pdf, doc, html ...) will have the wrong time or even date when accessed from Linux.
I stick to manual settings, since I connect to internet only briefly, and my pc is also switched off most of the time.
Is there any way of synchronising the time settings in the two OS partitions?
Thanks, =TeeSquare=

Oh the ole windows vs linux time changes issue. you can fiddle with both and set both to local time to work off your system clock or have linux updated by internet.

look into your distro on how to sync via internet or set it to local time,

Thank you for the inputs and references -- I have saved the pages, and will study them carefully before trying to implement anything. Hope to report the problem as 'solved' in a day or two. =TeeSquare=

Solved. Thank you for the instructions -- now I have both Ubuntu and Windows showing the same time. The procedure was simple enough for changing linux RTC to local time zone, but it took me over two hours to understand and implement it (making notes along the way!).
The only commands required (after correcting local time in Windows) were:
" timedatectl set-local-rtc 1 --adjust-system-clock "
and
" timedatectl "
to check the result. Thanks again, =TeeSquare=

^ Glad you got it solved.
From a logical/ethical/philosophical point of view I think that Windows is doing it wrong here, therefore it should be fixed on the Windows side (that is possible with some registry key IIRC).
Feel free to ignore my ramblings - don't fix what isn't broken.
