Create A Countdown?

[AGMason]

So im doing a job for someone from gmodstore and i need a countdown timer that displays a live countdown on the side of the players screen. I've tied all avenues i could think of putting a timer.Create and referencing it in a draw.WordBox, ive tried that with timer.Simple and having that execute a draw.WordBox so it updates the time every 15 minutes with multiple timers and boxes but there were all failures. A simple task yet im having so much difficulty if anyone knows alternative methods or even could provide me with the code that would be much appreciated

You won't get any help for a paid addon here, if you can't do the job - don't apply.
