Please goto www.delorie.com and have a look back in time in the DJGPP
workers list and you will find allot of talk about this a few years
ago and what was done to fix it.

In summary:-
1) You did not indicate which version of the DJGPP LIBC you are using.
This makes a BIG difference on 2K.
2) Did you try it on DOS? Does it work, on DOS clock() works.
3) Give the latest DJGPP LIBC a go. Check out the DJGPP newgroup
archive at www.delorie.com for where to find 2.04
