Usage:
 hwclock [function] [option...]

Time clocks utility.

Functions:
 -r, --show           display the RTC time
     --get            display drift corrected RTC time
     --set            set the RTC according to --date
 -s, --hctosys        set the system time from the RTC
 -w, --systohc        set the RTC from the system time
     --systz          send timescale configurations to the kernel
 -a, --adjust         adjust the RTC to account for systematic drift
     --predict        predict the drifted RTC time according to --date

Options:
 -u, --utc            the RTC timescale is UTC
 -l, --localtime      the RTC timescale is Local
 -f, --rtc      use an alternate file to /dev/rtc0
     --directisa      use the ISA bus instead of /dev/rtc0 access
     --date     date/time input for --set and --predict
     --delay     delay used when set new RTC time
     --update-drift   update the RTC drift factor
     --noadjfile      do not use /etc/adjtime
     --adjfile  use an alternate file to /etc/adjtime
     --test           dry run; implies --verbose
 -v, --verbose        display more details

 -h, --help           display this help
 -V, --version        display version
