Balena Fin RTC How To?

How do I make sure the RTC is started and in sync?

Hey there @jsmedley ,

Assuming the RTC is setup fine, then you should be able to run hwclock -w to write the OS time to the RTC module, and once its in sync, you it should stay synced as long as you keep a battery on the RTC module.

Does BalenaOS connected to Balena Cloud automatically do this?

It should be done out of the box, but it’d be interesting to investigate if you find out that’s not the case. BTW, this is another thread you might find useful: Current state of hardware RTC support

It does work correctly. Just making sure as I was in the testing group and it was a fairly manual process at that time to start the clock and get it set.

Thank you for your help!
