[systemd-devel] use RTC date/time to set system date time

[Michał Zegan]

There are problems with log timestamps when you do that, and it is
probably why it was not done.
I am wondering if the only correct way isn't to do it in initramfs (if
it's systemd) before starting the journald, so that first saved logs
have correct timestamps?
