hdclock return Invalid argument

Moderators: chensy, FATechsupport

I have a Tiny4412, its was without battery a few month. Now, I put a new battery, but the hardware clock don't work.

# hwclock -s
hwclock: RTC_RD_TIME: Invalid argument

When I installd Android, the clock work fine. I installed Linux / UbuntuCore, the clock goes to 12-31-1969 21:00 and I can't update. Returns error.

How can I fix it?
Then what do you use? You have to use something to do it. What kind of 'solution' do you mean? You can set your clock once, again using ntp, but it will drift away slowly, NTP constantly readjusts your clock, therefor it is recommended to have.
