Hi, I would like to use SAS to calculate the time elapsed in minutes between two time series, start_time and end_time and store it in a third column, time_elapsed. The data looks as such and is stored in an excel spreadsheet in the following hour-minute format: start_time end_time 02:20 02:45 03:00 03:45 04:02 04:17 ... ... Is there anyone with an idea as to how to proceed? Thank you
