I have a piece of data that looks like this (string format):
started_on
01-JUL-21 09.58.02.755421000 AM
completed_on
01-JUL-21 01.48.46.568084000 PM
I am trying to convert it to 24 hour format so i'm able to subtract two values from each other. For example: this should be 3 hours 50 minutes or 230 minutes
