Date array to timestamp

Hello!

I have an n x 1 cell array read from a file with date info in each cell, like this:

DateValues = {'13:22:32';'13:22:42';'13:22:52';'13:23:02';}

What I would like to have is a vector with the time spent between the subsequent dates. I used this piece of code for converting the strings into number.

TimeStamp = cell2mat(cellfun(@(x) datenum(x,'HH:mm:ss'),DateValues,'UniformOutput',false));

The resulting array seems correct and I can easily generate the difference of two neighbouring values. However, what I receive, are values like 1.1574e-4, although from the read date values I can clearly see that the differences should be around 10 seconds.

Any idea how to solve the problem?

Doc says: "The datenum function creates a numeric array that represents each point in time as the number of days from January 0, 0000. "

10 seconds is 10/(24*60*60) days
