NAME
rtc – real–time clock and non–volatile RAM

SYNOPSIS
bind #r /dev

/dev/rtc
/dev/nvram

DESCRIPTION
The rtc device supports 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)).

SEE ALSO
auth(8), boot(8)
