Save real-time clock on reboot

Save real-time clock on reboot

For computers without a real-time clock, this utility enables to store the wall-clock on shutdown and restore it on boot, in order to minimize the drift as far as possible until e.g. NTP is used to set the correct date/time again.

Note that systems using UFS for the root fs won’t need this, as the clock is already restored from info in the UFS superblock.
