I work on an air-gapped Tails OS. And i need the time to be correct without having to set an Admin password. When i shut down windows and boot into tails the time is correct, its the local time. But when I boot from linux to Tails linux the time is utc. I tried changing the way in which my linux box saves time, i.e, - timedatectl set-local-rtc 1 --adjust-system-clock.
Hmmm, weird. Not sure. I will add more information, if I come up with a better idea. Perhaps, in the meantime, someone else will help more successfully.
What we’re doing is creating a symbolic link so that /etc/localtime points to the timezone file that has the offset from UTC… in my case that’s Australia/Perth - your’s will probably be different (but to confuse matters with a digression, there is another Perth, in Australia, on the island of Tasmania, just inland from the port of Devonport).
