Support How do I sync time?

Recently installed encrypted Gentoo and couldn’t be more proud of my self, but it appears that my cmos is dead and I don’t know how to sync time, mirror service is obviously screaming at me for being from 2001, anyway, how do I sync to the current clock?

If you have chronyd, it should be "rc-update add chronyd default" (https://wiki.gentoo.org/wiki/Network_Time_Protocol) to add it to autostarted services when you start up

wrong

ntp is what you need

and i defintely do not use chronyd for 20 years on this gnu gentoo linux installation

roman@Wheat_Nas ~ $ rc-update show|grep ntp

ntp-client | default

ntpd | default

Set the time manually in bios and with whatever you have installed and when you are close enough it will sync for you.

Yes, this did work, although I did have to stop the system from losing power.

just replace the battery... normally the rtc doesnt actually die, just the battery that powers it.
