Toss these files into your EDuke32 directory (which should have both EDuke32.exe and Duke3d.grp) and launch the game in EDuke32
via Time_EDuke32.bat. 

The following files are untampered originals:
-Time12.bat (old batch file; not compatible with EDuke32)
-TIME12.grp (data file)
-Time12.txt 
-time.con (renamed from game.bak)

The following are new files:
-Time_EDuke32.bat (batch file to launch Time TC demo in EDuke32)
-MSDN note 2026.txt (this file)
