How Do You Programmatically Set the Hardware Clock on Linux?

Linux provides the stime(2) call to set the system time. However, while this will update the system's time, it does not set the BIOS hardware clock to match the new system time.

Linux systems typically sync the hardware clock with the system time at shutdown and at periodic intervals. However, if the machine gets power-cycled before one of these automatic syncs, the time will be incorrect when the machine restarts.

How do you ensure that the hardware clock gets updated when you set the system time?

If the text editor is different than kubuntu (kate is the default in editor), use your own with the sudo command in terminal.

  1. run terminal
  2. copy and paste this command sudo kate /etc/default/rcS press Enter
  3. enter user password (your login password) press Enter
  4. text editor will open on the desktop
  5. change the line UTC=yes to UTC=no
  6. and click save (at top of text editor tab bar)
  7. reboot
