TimeSync BBB rev C with time server on local network.

Hi,

How do I time sync my BBB with time server present on my local network.
At times, time also sets back to Mar 1 2015 after reboots.

Please advise.

Regards

Hi Vasanth,

Beaglebones Blacks do not have a real time clock and thus require time synchronization after each boot. We have taken several approaches to time synchronization over the years. The simplest approach is to give your Beaglebones access to the Internet, specifically pool.ntp.org. Our current approach is to use our Cisco router as a NTP time server. To do this, we had to configure DHCP Option 42 in the DHCP pool configuration to the address of the router and point the router to the US NTP pool. Neither of these options require edits to the Beaglebone's NTP configuration file at /etc/ntp.conf although your eventual solution may be different.

I would suggest searching Beaglebone or Linux forums for time synchronization options and setup assistance. I've copied a link below that might be a good place to start.
