I'm not sure I understand the question, but if you are talking about edu.wpi.first.wpilibj.Timer.delay(), then it does what it says - it causes the calling thread (your program) to pause for a while.

Oh - is the problem that the robot is pausing instead of driving (or whatever) for the expected time?

In that case it could be a watchdog problem? You need to keep feeding it, and if your delays are longer than the watchdog expiration it will time out.
