Well, it's does not directly related to a bug but it is in some way
related to:
https://bugs.mageia.org/show_bug.cgi?id=3817

As I mentioned in my original mail, as the hwclock is not clobbered on
shutdown with whatever random value we have in the system clock, we need
to be more tolerant of errors in time offsets.

If the user runs ntpd and doesn't drift too much then the RTC will be
sync'ed every 11 minutes by the kernel. If the drift is too high, or the
user does not run ntpd, then there will be no system clock to hwclock
sync as we simply don't have enough info to know we're correct.

This patch will avoid any fallout from this.

So I think it's likely still important to have in mga2.
