Time updating issue


We found that after shutting down Nano develop Kit and pull out the power cable, then the system time will go back to year 1980 or the time will keep at the time when it was shut down without connecting to network.
So, the time doesn’t update itself to the latest time when Nano device is shut down and pulled out the cable
How to make the Nano system time at latest time?

The Nano Devkit doesn’t have a battery-backed real time clock. Without modifying the carrier board to add a battery or super capacitor, the rtc may get set back to 1980 or some other time depending on how long the power was out.

Got it, Thanks
