What is the "Auto-Reboot" used for? I had 2nd thoughts using it coz it only shows time which means it has to reboot daily. I was thinking maybe auto-rebooting weekly or every 2 weeks.

I'm not really having issues on both my cameras. I only thought it might have good effect since it's part of the cameras' features. 

If you can shed more light - technically or otherwise will be highly appreciated. Thanks!
