NAME
rtc - real-time clock and non-volatile RAM
SYNOPSIS
bind #r /dev /dev/rtc /dev/nvram
DESCRIPTION
The rtc device supports the Mostek MK48T12-15 Zeropower/Timekeeper and similar devices with real-time clocks and non-volatile RAM. 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)).
