XTCLK
DESCRIPTION
The XTCLK utility has two functions. It can either set the DOS time and date from the battery-
backed real time clock, or it can set the time and date of the battery-backed real time clock from the
DOS clock.
OPERATION
To use the XTCLK program to set the DOS time and date, simply type its name on the command
line and press enter. It will copy the contents of the battery-backed real time clock to the DOS time
and date. To automate the process of initializing the DOS clock at boot time, install the command
in the system's AUTOEXEC.BAT file.
To use the XTCLK program to set the battery-backed real time clock to the DOS time and date,
execute the following command at the DOS prompt:
XTCLK -s
The -s switch tells the program to write the current DOS time and date into the battery-backed
clock. You can set the DOS time and date to the current time and date with the DOS commands
TIME and DATE.
