A runtime error will be encountered if:

  • the specified 2 digit date value exceeds the number of days in that month.

The function returns a null value if:

  • the hour value, or the minutes value, or the seconds value is specified in more than 2 digits.
  • the date value is specified in more than 2 digits.
  • the year value has more than 4 digits.
