Hi! I am EXTREMELY wet behind the ears in SAS. I have data of medical providers and how long they recorded temperatures in their vaccine storage units. The amount of time that these providers were recording temperatures in their refrigerators and freezers is presented in a DATE/HH:MM format. I need to create a new variable (duration), that subtracts the End time from the Start time to determine the total time they were recording. The data in my new duration variable should be presented in HH:MM:SS format. I will need to manipulate the HH:MM:SS data in the duration column in different ways by provider, so I need SAS to continue to recognize it in this format and add them correctly. Date/Time Start Date/Time End (New Variable) Duration 10/31/13 10:27 10/31/13 15:27 5:00:00 9/27/13 9:15 9/28/13 12:00 26:45:00 9/28/13 12:15 9/28/13 13:15 1:00:00 10/1/13 8:01 10/1/13 8:36 00:30:00 Need to be able to add Duration correctly - 33:15:00 I found the following INTCK statements that seem as though they may be on the right track of giving me what I need, however, the statements split out the hours/minutes/seconds. It doesn't give me the duration in the hh:mm:ss format. Datetime arguments: hours=intck ('hour' , '01jan2009:00:00:00'dt, '01jan2010:00:00:00'dt); minutes=intck ('minute' , '01jan2009:00:00:00'dt, '01jan2010:00:00:00'dt); seconds=intck ('second', '01jan2009:00:00:00'dt, '01jan2010:00:00:00'dt); The result values will be: *hours = 8760 *minutes = 525600 *seconds = 31536000
