If necessary, you can set your hardware clock to synchronize with UTC by entering the following command: timedatectl set-local-rtc 0Īs with the previous command, there is no confirmation that the change has applied.

You may get an error in this mode, since updating the hardware clock to the local timezone is unsupported. To have your Real-Time Clock synchronize to your local timezone enter: timedatectl set-local-rtc 1 Set Hardware Clock to Sync to Local Timezone Your system has a tiny quartz crystal and a battery that keeps time at times when the system disconnects from a network. RTC stands for Real-Time Clock, another name for the hardware clock in your computer. They are equivalent terms when fractions of a second are not relevant.
