Date and time synchronization

I had installed LinuxCNC a few months back, but I didn't use it. I tried two days back to install Arduino, and the date is showing wrong on the taskbar, and I am unable to connect to the internet for browsing.

Let me know what I can do best. I always check the CMOS battery on Windows to see if it is good or not, but this motherboard is under warranty.

I think that, if you connected to the internet, the date and time would correct themselves. So I would start with debugging the internet connection.

The internet is connected, but the browser is not allowed to browse because of the date and time. When I installed LinuxCNC, everything was working.

This is a general Linux / Debian question rather than a LinuxCNC question, so you might need to broaden your search.

Might help?
