How to change data in a cell array of doubles?

I have attached the variable that I am trying to change. The first column in each double is time. I would like to go through all the trials and fix the time so that it starts from 0, by doing time = time - 1
Time for the first trial (portion).

??? "doing time = time - 1" doesn't "fix the time so that it starts from 0"
Try this
>> load('trials.mat')
>> cac = cellfun( @(num) num-[num(1,1),0,0,0,0,0,0], trials, 'uni',false );
>> trials{1}(1:6,:)
ans =
9.6994 0 2673.3 0 4.93 0.41 600
9.7405 0 2673.7 0 10 0.41 600
9.7505 0 2674.1 0 40.91 0.82 600
9.7591 0 2674.5 0 47.96 1.23 600
9.7681 0 2674.9 0 46 1.64 600
9.7823 0 2675.3 0 28.91 2.05 600
>> cac{1}(1:6,:)
ans =
0 0 2673.3 0 4.93 0.41 600
0.041117 0 2673.7 0 10 0.41 600
0.051163 0 2674.1 0 40.91 0.82 600
0.059732 0 2674.5 0 47.96 1.23 600
0.068666 0 2674.9 0 46 1.64 600

I don't know how to answer.

Do some experiments, e.g.
>> m = magic(3)
m =
8 1 6
3 5 7
4 9 2
>> m - [m(1,1),0,0]
ans =
0 1 6
-5 5 7
-4 9 2
