Hi I have a matlab serial date number as this t1= 7.316213854513889e+005 New times will arrive and I need to check if the difference of t1 and the next is greater than 10 minutes. If true {do something} else {do another task}

According to the documentation for 'datenum' at:

http://www.mathworks.com/help/matlab/ref/datenum.html

"A serial date number represents the whole and fractional number of days from a fixed, preset date (January 0, 0000)." Hence ten minutes would be this fraction of a day:

10/60/24 = .006944444....

so if your next serial date number differs from t1 by more than that amount, you should "do something".
