'Date' is a program to set the date and time of your computer if you do
|
|
not have a clock built in to your computer. This program will not change
|
|
the date on your clock but only change the bytes in ProDOS. This program
|
|
was designed to be included in the %autoexec file. For example, add the
|
|
following line to your file: "date -s." See below for the explanation of
|
|
the -s option.
|
|
|
|
With no options, 'date' will print the current date and time and ask for
|
|
the new date and the new time. The format for the date is DD-MMM-YY. The
|
|
format for the time is HH:MM in 24 hour format. If the date or time is
|
|
entered incorrectly, or you just press return when prompted, 'date' will not
|
|
change the current values. Options are as follows:
|
|
|
|
-p: print only -- When this option is used, 'date' will only print
|
|
the date and time currently on the system.
|
|
|
|
-s: set date/time only if not already set -- This option will only
|
|
prompt you to set the date and time if the date and time have not
|
|
already been set. This option is useful in the %autoexec startup
|
|
file. You will be prompted once on bootup to set the date and time.
|
|
When you re-enter Davex after quitting from an application, 'date'
|
|
will not ask you to change the date since you already set it on
|
|
bootup.
|
|
|
|
-d: date -- Use this option in conjunction with the -s option.
|
|
This will force the program to always set the date even if the
|
|
date has already been set. Time setting remains the same as
|
|
with the -s option.
|
|
|
|
-t: time -- Use this option in conjunction with the -s option.
|
|
This will force the program to always set the time even if the
|
|
time has already been set. Date setting remains the same as
|
|
with the -s option.
|
|
|
|
-f: get date/time stamp from file -- This option will set your system's
|
|
date and time equal to the last modification date and time field
|
|
from the file given after the option. This option is only effective
|
|
when the date and time is not set. Use this option in your autoexec
|
|
file to set the your system time on bootup. Example autoexec file:
|
|
|
|
date -s -t -f"%time.stamp"
|
|
touch %time.stamp
|
|
|
|
The first line will grab the time from the file "time.stamp" in the
|
|
Davex directory when first booting up the computer. Every time you
|
|
rerun Davex after exiting from a sys program, you will be prompted
|
|
to change only the time. The second line keeps the date current
|
|
on the file "time.stamp" so it reads in the most current date when
|
|
you reboot the computer.
|
|
|
|
Notes: If the -p option is included along with the -s option, 'date' will
|
|
ignore the -s option and only print the date and time.
|
|
|
|
When you use the -t option and the newly entered hour is less
|
|
than the current hour, 'date' version 1.2 will increment the
|
|
date by one day, changing the month and year if necessary.
|
|
|
|
The command 'date -s -d -t' performs the same functions as the
|
|
command 'date' with no options.
