# 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.
