rtc – real–time clock and non–volatile RAM|
bind #r /dev |
The rtc device supports devices with real–time clocks and non–volatile
The rtc file behaves just like /dev/time (see cons(3)). The real–time clock is maintained on–board; /dev/time is set from the file server. Neither is necessarily more accurate.
The nvram file provides (if permission allows) access to the local
non–volatile RAM. For example, boot(8) reads the machine's key
from there (see auth(8)).
