I've been noticing a peculiar issue with Ubuntu recently, in that booting to Ubuntu from Windows seems to be messing with the System time.
Eg: I shutdown Windows at 8:35pm, to boot into Ubuntu. When Ubuntu was started up, instead of showing time as 8:35 pm, it showed 3:05 pm momentarily, before setting itself to 8:35pm. If Windows is restarted after this happens, time now becomes 3:05pm (which seems to be UTC time)
If Windows alone is restarted (Meaning booting up Windows after shutting down Windows), no time fluctuation occurs. If Ubuntu is started up after Windows is shutdown, the same issue happens. Time seems momentarily UTC, and then corrected within a second or so after startup, to correct time. However the next time Windows is booted up, the time becomes the same as that which was momentarily displayed on Ubuntu. I hope I'm making this clear.
I've checked that my timezone is correct in Ubuntu. It is set as Asia/Kolkata. I even did a
dpkg-reconfigure tzdata, but it was already correct timezone.
My timezone is Asia/Kolkata, which is UTC+5.30 hours. The time which appears incorrectly is the correct time if my timezone was UTC. I have a Multiboot with grub2, managing Ubuntu 13.04 and Windows 8. PC is an Acer Aspire V5-121 Netbook purchased two days ago.
I'd love any help with deciphering this apparently weird mystery.
