Use etime function
v={'1/28/2016 2:23:31.996 PM'  '1/28/2016 2:25:27.808 PM'
'1/28/2016 3:20:30.925 PM'  '1/28/2016 3:22:29.174 PM'
'1/30/2016 11:18:09.333 PM'  '1/31/2016 12:59:41.693 AM'
'1/30/2016 11:18:09.333 PM'  '2/1/2016 1:24:00.083 AM'
'2/1/2016 2:50:13.521 AM'         '2/1/2016 2:52:05.412 AM'}
c1=datevec(v(:,1),'mm/dd/yyyy HH:MM:SS.FFF')
c2=datevec(v(:,2),'mm/dd/yyyy HH:MM:SS.FFF')
d=etime(c2,c1)
