Error on converting datestr to datenum

Here is my code :
time0=200;
formatOut = 'yyyy-MM-dd HH:mm:SS';
t{1}=datestr(now,formatOut);
for i=2:length(time0)
 t0=datenum(t{i-1}); 
 t2=(addtodate(t0,2,'second'));
 t{i}=datestr(t2);
end
ch=t;
t = datetime(ch,'InputFormat','yyyy-MM-dd HH:mm:SS');

I want to simply create a data stream by adding in first time step(getting real time) 2 seconds in each time step.And then Hold all this values in a datetime format(it has to be for my needs in this format).

But when i run my script i get this error:

"Error using datetime (line 602)Unable to parse date/time text using the format 'yyyy-MM-dd HH:mm:SS'."

Is there any tip?

The correct format is 'yyyy-MM-dd HH:mm:ss'.

However, there is a much easier way to create your datetime array:

t0 = datetime('now');
tv = t0 + seconds(2:2:200);
