Settings for readtable for date and timestamp columns

I have a CSV file that looks like this and I want to use readtable() to load up the Date and Time columns so that they are numerical. (rather than 'cell' or 'string').
Is there a set of options for doing that in readtable? I know I can loop programmatically and convert each entry from char/string with datenum but want to avoid that overhead.
I have tried
T = readtable( filename, 'Delimiter', ',' ...
, 'HeaderLines', 0 ...
, 'ReadVariableNames', true ...
, 'Format', '%s%s%s%f%f' ...
, 'FileType', 'text' ...
, 'ReadRowNames', false ...
, 'TreatAsEmpty','N/A' ...
, 'TextType', 'string' ...
, 'DatetimeType', 'datetime' )

Which MATLAB release are you using? Dealing with times got easier in recent releases.
Is it really necessary that you use numeric entries for those? Most of the time it makes more sense to combine the date and time into a single datetime object.
