Two timers with same total time will slowly lose sync with eachother.

Did you set them directly or via sliders? May be some issue with the limited resolution of single-floats or some race-condition. 

I set them directly in the text boxes I'm pretty sure

I did some more testing. It seems that timers will stay in sync if their on/off times are the inverse of eachother.

A timer with 2/8 syncs perfectly with a timer with 8/2.

A timer with 1/9 syncs perfectly with another 1/9 timer.

A timer with 1/9 loses sync with a timer with 2/8.

A timer with 2/3 loses sync with a timer with 1/4.

I would attach a save file but this is from my 'testing world' save and its over 2MB.

They probably are running into some rounding errors when they convert a setting to ticks on and ticks off. May be the low "Float" precision striking again. They should probably normalize all input to ticks directly and eliminate conversion completely. Of course, I could be completely off about this, as I have not looked at the code.

It would actually be amazing if timers were two tiles tall, and included a 'reset' input

check this, its just pure automation, and the ticks dont have the same lenght. At every 6th loop the door dont open totaly and dont let the gas move in.
