Return_Value

   A character string containing the current date and time. The
   returned string has the following fixed, 23-character format:

   dd-mmm-yyyy hh:mm:ss.cc

   When the current day of the month is any of the values 1 to 9,
   the first character in the returned string is a blank character.
   The time portion of the string is always in character position
   13, at an offset of 12 characters from the beginning of the
   string.

   Note that you must use the assignment operator (=)  to preserve
   the blank character in the returned string. If you use the string
   assignment operator (:=),  the leading blank is dropped.
