You might find this helpful.  It is from the documentation in the CONFIG helper
application which I clipped and also added what would be needed for me here in
Central Texas:

Daylight savings time in OS/2 can easily be changed for whatever.  The time
zone variable in the OS/2 CONFIG.SYS file line normally only looks like: 

                           SET TZ=CST6CDT 

But the following options can be added to move it off the default as follows: 

           =SSS[+|-]nDDD[,sm,sw,sd,st,em,,ew,ed,et,shift]

Values:

SSS   Standardtimezonedescriptor, default EST positive values are west 
      of 0 degree length negative values are east of 0 degree length

n     Difference to Greenwich Mean Time in Hours, default 5

DDD   Daylightsavingsdescriptor, default EDT

sm    Month in which Summer Time starts, default 4

sw    Week in which Summer Time starts, default 1. Positive values are 
      counted from the beginning, negative values are counted from the 
      end of the month

sd    Day at which Summer Time starts, default 0. 0 is Sunday ( 1 Monday ...) 
      if the week is unequal zero (0), when the week is zero it counts 
      the day of the month (1 to 31).

st    Time of Summer Time start in seconds, default 3600

em    Month in which Summer Time ends, default 10

ew    Week in which Summer Time ends, default -1. See sw for description

ed    Day at which Summer Time end, default 0. See sd for description

et    Time of Summer Time end in seconds, default is 7200
 
shift Size of the Time shift in seconds, default 3600

           http://redrival.com/os2util/index.htm

In our case here in the Central Time Zone this becomes: 

      SET TZ=CST6CDT,3,2,0,7200,11,1,0,7200,3600

CONFIG.SYS needs to be altered by QE or QO editor in our case which does *NOT*
end the file with an ASCI CHR(11) like WordStar!   Also note the CONFIG.SYS
really needs at least one blank line at the end for some purposes! 


--> Sleep well; OS/2's still awake! ;)
