Issues with System Settings Time

We just posted an Interceptor OS update regarding this: https://www.axzez.com/axzez-news (April 16, 2022 - Interceptor OS Update).

So there is a linux kernel bug with enabling battery backup for the rv3028 rtc. We workaround this with a script that executes when the installer runs. If you did not have the battery installed or removed it since running the installer, battery backup does not work, and you will see a low voltage warning in dmesg. I've pasted the script below. We should probably also execute this script when using the system settings tool.

  # check level switching mode
  local backup=$(i2cget -y 0 0x52 0x37)
  if (((backup & 0x0c) == 0x0c)); then
    echo 'Battery backup already enabled.'
    return 0
  fi

  echo 'Enabling battery backup...'

  # disable auto refresh
  local control=$(i2cget -y 0 0x52 0x0f)
  i2cset -y 0 0x52 0x0f $((control | 0x08))

  # enable level switching mode
  i2cset -y 0 0x52 0x37 $((backup | 0x0c))

  # update eeprom
  i2cset -y 0 0x52 0x27 0x00
  i2cset -y 0 0x52 0x27 0x11
  sleep 1

  # enable auto refresh
  i2cset -y 0 0x52 0x0f $control

I am using the supplied interceptor OS. I am clicking on Apply.

Thanks @Bill Clark for the note. This should survive reboot. Are you currently using the Interceptor OS that we provide, or something else? If the Interceptor OS that we provide, please ensure that, after you set the new timezone, you click the "Apply" button or your changes will be lost.
