Create duration array template

I need to create a duration array as below. However, instead of getting tx with a length of 720000, Im getting 7200000001?

The context is that I will create this array as a timestamp template to then match my recorded times (and corrsponding data) with the closest time in this template.

ti = duration('00:00:0.00','Format','hh:mm:ss.SSS');

tf = duration('02:00:0.00','Format','hh:mm:ss.SSS');

interval = milliseconds(0.010);

tx = ti:interval:tf;

Cheers

ti = duration('00:00:0.00','Format','hh:mm:ss.SSS');
tf = duration('02:00:0.00','Format','hh:mm:ss.SSS');

interval = milliseconds(0.010);

% number of points
n = 2*3600/(0.01e-3)+1

n = 720000001

% to make 720000 points
interval = seconds(0.010);

tx = ti:interval:tf;

Many thanks, it was seconds not milliseconds!
