MATLAB: Datetime conversion in numeric form (matrix)

Question

So, I have been trying to convert date to a number and add it to the first column of a numeric matrix.

Unfortnatelly, I use the code below to create the matrix for a specific range of dates but the dates were imported as strings not numbers (see picture). i have no dea why this doesn't work. Any idea?

t1=datetime([2001 01 01 00 00 00]);
t2=datetime([2017 12 31 23 00 00]);
t=[t1:1/24:t2];
time = datetime(t); %this is where the conversion should have happened
time=time';

Firstly, I set the starting and finishing point and then, I choose to insert data by the hour.

After that I try but fail to do the numeric conversion.

Any help is appreciated!

If you want to convert them into date numbers, use the datenum function:

timeNr = datenum(time);

If you want to convert them into something else numeric, please be specific.
