I need to change the time intervals on a time sheet form that our clients enter their student hours. Currently we are Forms Ver. 11.0 and the intervals are set to 1 hour, instead of 15, 30, or 60. I have seen in past posts that people got around this by using Javascript but that was back in 2017. 

I set the time interval to 15 min by using a dropdown list for Time in and Time out in a collection. It works but is not ideal for what we are wanting to do because I must use military time in order to get the calculations to work properly. 

Surely, someone has an answer that can point me in the right direction. Fingers crossed!!!!
