Always much easier if you attach the actual code you've used to get to this point and a little bit, at least of the data array. Attach a .mat file is simple way to do that..
But, couple comments -- why a cell array of just one element per cell all of the same type? Why not just an array?
Probably the simplest is to use something like (I'm guessing on the datatypes here since we don't have enough to go on...)
Salt to suit actual storage types you have or, I'd suggest to remove the cell array if isn't needed and you might be able to dispense with using a duration array here as well in lieu of just numeric times. durations have their uses, but they come with warts as well...
