It could be that your code takes 100ms to execute after the timer hits. It could also be that, afaik, the scripts are run as a single thread, which means one thing has to finish before another thing may begin. Example: You have two systems, a drug system and a job system. If the drug system is on a timer and it is set to be executed in 1000ms. It could be executed at 1100ms if the job system needs to do some work right before it.
