[Bug 1696981] [NEW] fixrtc is ineffective when there is no battery for the RTC

[Alfonso Sanchez-Beato]

Public bug reported:

When there is no battery for the RTC, fixrtc is not able to find a good
enough date. To fix the clock, this script is using the last time the
root filesystem was mounted, but as that is done before there is any
network, and as after a reboot/poweroff the RTC time is always reset
(because time is not kept due to lack of battery), the mount time will
never be good.
