MATLAB Function Reference Volume 1: A - E - Bad Request

datestr
2-372
NOTE dateform numbers 0, 1, 2, 6, 13, 14, 15, 16, and 23 produce a string
suitable for input to datenum or datevec. Other date string formats will not
work with these functions.
Time formats like 'h:m:s', 'h:m:s.s', 'h:m pm', ... may also be part of the
input array DT. If you do not specify dateform, or if you specify dateform as -1,
the date string format defaults to
1 if DT contains date information only (01-Mar-1995)
16 if DT contains time information only (03:45 PM)
0 if DT is a date vector, or a string that contains both date and time
information (01-Mar-1995 03:45)
