Why not the "Current date is" text? If you're trying to put entries
into a log file from a FreeDOS BAT file, you presumably aren't dumping
a ton of output into the log (my guess: you probably aren't writing a
ton of output to the log file, perhaps noting when a job was last run,
and probably copying the output of a command). Assuming you're just
looking to put the date and time in a log file, from a BAT file, DATE
/T and TIME /T will make a timestamp of when the command was run.
Or if you just want a program to generate the date and time, you could
do something like this:
#include <stdio.h>
#include <dos.h>
int
main()
{
struct dosdate_t dt;
struct dostime_t tm;
_dos_getdate(&dt);
_dos_gettime(&tm);
printf("%d-%d-%d %.2d:%.2d:%.2d\n", dt.year, dt.month, dt.day,
tm.hour, tm.minute, tm.second);
return 0;
}
For example, if you save this as NOW.C and compile it to NOW.EXE
(using OpenWatcom C, with -ox will generate an 8k binary) you will get
output like this:
C:\> NOW
2022-12-23 17:59:54
And you can easily append that output to a file.
