NAME
adjtime_config - information about hardware clock setting and drift factorSYNOPSIS
/etc/adjtimeDESCRIPTION
The file /etc/adjtime contains descriptive information about the hardware mode clock setting and clock drift factor. The file is read and write by hwclock(8); and read by programs like rtcwake to get RTC time mode.First line
Three numbers, separated by blanks:the systematic drift rate in seconds per day
(floating point decimal)
the resulting number of seconds since 1969 UTC
of most recent adjustment or calibration (decimal integer)
zero (for compatibility with clock(8))
as a floating point decimal
Second line
last calibration timeThe resulting number of seconds since 1969 UTC
of most recent calibration. Zero if there has been no calibration yet or it is
known that any previous calibration is moot (for example, because the Hardware
Clock has been found, since that calibration, not to contain a valid time).
This is a decimal integer.
Third line
clock modeSupported values are UTC or
LOCAL. Tells whether the Hardware Clock is set to Coordinated Universal
Time or local time. You can always override this value with options on the
hwclock(8) command line.
