    It means that "last time - current time" is smaller than 0
    You are traveling back in time.

    These things can happen with overclocked or broken hardware.
    Or it could be a bug in the runtime because of some special behavior of you CPU.

    I was able to fix the Negative Delta Time! problem by running UT2003 in Windows98/ME compatibility mode.:D

    And to do what uncover just said, right click on the game's shortcut, go to properties. There click on the compatibility tab. The add a check box to "run this program in compatibility mode for" and choose "win 98/me".
