Sorry but I cant for my life figure out how to post a change request.

Fork with timedrift fix

Instead of this, it handles the time drift that is created by the program while it runs. For instance if your program run for 4seconds and you want to run it each second. This original will run 60times, once for each second. 60 * 5 = 300. This will make your system have 5 sets of processes run at each time, NOT what you wanted.
My fix is not perfect, but it's a huge improvement.

@keylase if you still use this I assume you want to incorporate the changes I made, I assume you will not have any problem understand what the code does.

Thank you! it looks good - fixed 😄
