Everytime I use Mint 17.3 or 18, from a USB flash the clock is wrong, but I don't care in Linux. However when I subsequently restart to Windows 7, that clock is wrong. In fact today about 11pm it got changed to tomorrow. it's UTC time, I think 4-5 hours ahead. Is there a way to fix that? I do use persistent setting - would that help?
Yes , probably . I have many Linux distros on USB and this is a persistent ( pun intended ) problem when running live . If you have persistence set up , go to settings -> time/date -> select your time zone It normally works I usually test persistence by putting a simple text doc on the desktop and check if it is still there on reboot.
Thank you both. Persistent setting of time zone worked. It no longer affects Windows 7 and Windows 10 startups Live Mint still boots with UTC time set, but changes to the correct zone within few seconds. Works very fast from a USB3 flash. I'm still reluctant to install it since M$ might mess me up with their Windows 10 unsolicited updates.
Just bumped into this article http://www.webupd8.org/2014/09/dual-boot-fix-time-differences-between.html which explains why "timedatectl set-local-rtc 1" that Brian K suggested works so that Mint doesn't ruin the Windows clock.
