Live-usb writes UTC time to hwclock [Solved]

[figueroa]

Although I do not dual boot, as a practice carried over from early PCs with battery-backed real-time-clocks and MSDOS, I've always set BIOS HWCLOCK (RTC) to local time. I've just figured out that whenever I boot antiX or MX installation media without setting the timezone and/or the option hwclock=local, my hardware clock gets reset to UTC.

I think this is a problem. Installation media should not be writing to the PCs hardware clock.

hm...I'll look into it. our live version of the hwclock init script shouldn't touch the clock, so this would certainly be a bug.

I think I found the issue, but haven't tested my fix yet. If you are using persistence, you can edit the /etc/init.d/hwclock.sh file by removing

Code: Select all

if mountpoint -q /live/aufs; then
	verbose_log_action_msg "Not setting hardware clock on Live system"
	exit 0
fi

and replacing with

Code: Select all

if [ -d "/live/aufs" ]; then
	verbose_log_action_msg "Not setting hardware clock on Live system"
	exit 0
fi
[code]

Not here, checked within BIOS and set manually to localtime. After booting live media and rebooted into BIOS setup, it stays in localtime.

actually fehlix is right. now that I'm at a pc to test, I can't duplicate the problem, at least not with MX 21.

Thanks for checking. I'm going to mark this as solved. With apologies, apparently it's not antiX or MX, it's my failure at interpretation. When I check differently, it's more clear; and I'm blushing:

Code: Select all
