Why if I will disable internet connection on my router and reboot it, it shows incorrect time (0:00)?

I reboot one of my ar300m routers, that is being used as a VPN server, daily using something similar to this:

30 10 * * * sleep 70 && touch /etc/banner && sync && reboot

The startup time that the router starts with, changes everyday to the timestamp I set on the file /etc/banner using the touch command. The sleep 70 && touch /etc/banner is to make sure the router time is set to be after the reboot time, or it is possible to get the router stuck in a reboot loop.

See:

Nightly Reboot of GL-AR750?

You can schedule tasks with cron: Specifically: Reboot at 4:30am every day Note: To avoid infinite reboot loop, wait 70 seconds and touch a file in /etc so clock will be set properly to 4:31 on reboot before cron starts. 30 4 * * * sleep 70 && touch /etc/banner && reboot So from gl-inet web interface go: More settings > advanced > system > scheduled tasks Howevre, you have to first ‘restart’ the Cron service to make your edits stick by visiting: More settings > advanced > sys…

Once the WAN comes up, the time on the router jumps forward to the correct time.
