How can I add 5 seconds to the output of the CLOCK function in MATLAB 7.9 (R2009b)?

The CLOCK function returns a 1x6 vector. I want to compute "clock + 5 seconds".

For example:

>> clock

 ans =

          2009           10            6           14           18        9.125

I want to compute clock + 5 seconds, and get a vector [2009 10 5

12 40 01].

To do this, you can use the DATENUM and DATEVEC function as an intermediaries:

     second = [0 0 0 0 0 1];

     datevec(datenum(clock + 5* second))

You can extend this idea to perform any arbitrary day arithmetic:

     year = [1 0 0 0 0 0];

     month = [0 1 0 0 0 0];

     day = [0 0 1 0 0 0];

     hour = [0 0 0 1 0 0];

     minute = [0 0 0 0 1 0];

     second = [0 0 0 0 0 1];

     datevec(datenum(clock + 5*second + 4*month + 3*hour + 13*year));
