Convert datetime to default format

My input date time is 16:30:00 13-05-21. It's in HH:MM:SS dd-mm-yy format. I need to convert it into default format like this (13-May-2021 16:30:00).

I tried this but, the output comes out as NaT .

inp_time='16:30:00 13-05-21';
>>  dtime=datetime(inp_time,'InputFormat','HH:MM:SS dd-mm-yy')
dtime= NaT

Can you help me here?

inp_time='16:30:00 13-05-21';
dtime=datetime(inp_time,'InputFormat','HH:MM:SS dd-mm-yy')

Warning: The format 'HH:MM:SS dd-mm-yy' contains a field for minute (m) in what appears to be a date portion. You might have intended to use the symbol for month (M) rather than for minute (m). See the datetime.Format property for a complete description of the identifiers used in datetime formats.

Have you tried swapping the M and m parts of the InputFormat as suggested by the warning messages?
