how to convert datetime array to double

How can I convert the datetime array to Double? for example,

>> dt = datetime( '08:07:53', 'InputFormat', 'HH:mm:ss' );
>> dt.Format = 'HH:mm:ss';
>> T1 = (dt + hours(1:5)+seconds(1:5))' 

Thanks!!

You probably don't need to convert to double. What are you trying to do?

You almost certainly do not want to convert '08:07:53' to a datetime, unless you mean "08:07:53 today", where the definition of "today" changes every day.

If you want to use gridded interpolation of a variable versus a datetime array you have to convert the date to double viz:

Error using griddedInterpolant

The input points must be a single or double array.
