I have a need to find the elapsed time between two datetime fields. I need to find the downtime between the end of one job {incendent.timeinservice}to the start of another job {incendent.timealerted} for each truck {incendent.unitid}. Each job(incendent.id)has it's on entry into the database. The times might span from late one night to early the next morning or be within the same day.I ony need the hours and minutes of, or just minutes of downtime. Thanks.
