Converting millisecond to time read out hh:mm:ss

I’m trying to take the millisecond count down timer from my plc and display it on ignition. Any ideas?

I couldn’t find a pre-made digital clock so I tried scripting and even thought about linking several LED displays to ignition timers with set values and running property bind to trigger to run PLC timer so that it’s not reading it but rather running at the sam time but ran into problems having them stop at 0 and reset when counting down (Sec would need to do this is the time is longer then a min.
