Date Calculations - minutes and seconds
I am working on trying to find out how to calculate the time difference between dates.
Here is what I am after:
I would like to see the difference lets pick two dates start (created_date) - end (posted_date). I would like the output to show the time in minutes:seconds or minutes.seconds of the lapse between the time. If you also apply that same formula that will be generated to another set of dates, lets say start (completed_date) - end (promised_time) will the output be more or less the same or will the calculation need to be different for the latter?
I appreciate your help in advance.
