Dim hour As Integer = moment.Hour

' Minute gets 57.
Dim minute As Integer =
 moment.Minute

' Second gets 32.
Dim second As Integer =
 moment.Second

Dim millisecond As Integer
 = moment.Millisecond

System.DateTime moment = new System.DateTime(
                                1999, 1, 13, 3, 57, 32, 11);

int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;

C++

System::DateTime moment = System::DateTime(
   1999, 1, 13, 3, 57, 32, 11 );

// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;

System.DateTime moment = new System.DateTime(1999, 1, 13,
                        3, 57, 32, 11);

// Year gets 1999.
int year = moment.get_Year();

// Month gets 1 (January).
int month = moment.get_Month();

// Day gets 13.
int day = moment.get_Day();

// Hour gets 3.
int hour = moment.get_Hour();

// Minute gets 57.
int minute = moment.get_Minute();

// Second gets 32.
int second = moment.get_Second();

// Millisecond gets 11.
int millisecond = moment.get_Millisecond();
