MATLAB: How to find time difference between two times

time difference

t1={'01-Oct-2011 11:12:00'};
t2={'01-Oct-2011 11:15:00'};
t11=datenum(t1(:));
t22=datenum(t2(:));
I have two times. How can i find difference in seconds between them?

The etime function does exactly what you want. You have to convert your times to date vectors first:
t1={'01-Oct-2011 11:12:00'};
t2={'01-Oct-2011 11:15:00'};
t11=datevec(datenum(t1));
t22=datevec(datenum(t2));
time_interval_in_seconds = etime(t22,t11)
time_interval_in_seconds =
     180.0000
