  function IsValidDateTime(const AYear: Word; const AMonth: Word; 
                          const ADay: Word; const AHour: Word; 
                          const AMinute: Word; const ASecond: Word; 
                          const AMilliSecond: Word) : Boolean;

Description

IsValidTime returns True when the values AYear, AMonth, ADay, AHour, AMinute, ASecond and AMilliSecond form a valid date and time indication. If one of the values is not valid (e.g. the seconds are larger than 60), False is returned.

AYear must be in the range 1..9999 to be valid.
