Hi,
This is so simple!  Just use the DATETIME structure to set and get date and
time.  There are other ways, but this seems to be a simple one.  If you
look inside the OS2EMX.H file, and look under the TIMERS section, you'll
find other things like seconds,hundredths,timezone,and weekday.  Also, get
the file PRCP.ZIP (I think it's called that).  It has PRCP.INF file which
gives you examples and meanings for different DOS APIs, etc..  That's where
I learned this (The below is from the example from PRCP.INF.  I Just
modified it a bit.).

#define INCL_DOSDATETIME
#include 

main()
{
DATETIME        DateTime;                       // Structure for date and time

DosGetDateTime(&DateTime);                      // Get date and time information

// Show current date and time
printf("Today's date is %d//%d//%d and time is
%d:%d\n",DateTime.day,       
DateTime.month,DateTime.year,DateTime.hour,DateTime.minutes);

// You can change the date and/or time to anything.  The below is an example
DateTime.day            = 8;            // Set day to 8
DateTime.month          = 9;            // Set month to 9 (Sepetmber)
DateTime.year           = 1999;         // Year to 1999
DateTime.hour           = 3;            // Hour to 3
DateTime.minutes        = 35;           // Minutes to 35

// Show new date and time
printf("New date is %d-%d-%d and new time is
%d:%d\n",DateTime.day,       
DateTime.month,DateTime.year,DateTime.hour,DateTime.minutes);

// Change to new date and time
DosSetDateTime(&DateTime);
}

Hope this helps!
Bye!
