# Rules for the hwclock_t domain.

# This domain moves time information between the "hardware clock"

# (which runs when the system is off) and the "system clock",

# and it stores adjustment values in /etc/adjtime so that errors in the

# hardware clock are corrected.

# Note that any errors from this domain are NOT recorded by the system logger,

# because the system logger isnt running when this domain is active.
