DateTime.Millisecond Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the milliseconds component of the date represented by this instance.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property Millisecond As Integer

public int Millisecond { get; }

Property Value

Type: System.Int32
The milliseconds component, expressed as a value between 0 and 999.

Remarks

You can display the string representation of the Millisecond property by using the "fff" format specifier. For example, the following code displays a string that contains the number of milliseconds in a date and time to the console:

Dim date1 As Date = New Date(2008, 1, 1, 0, 30, 45, 125)
outputBlock.Text += String.Format("Milliseconds: {0:fff}", _
                  date1)       ' displays Milliseconds: 125 & vbCrLf

DateTime date1 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
outputBlock.Text += String.Format("Milliseconds: {0:fff}",
                  date1) + "\n";           // displays Milliseconds: 125

You can also display the millisecond component together with the other components of a date and time value by using the "o" standard format specifier. For example:

Dim date2 As New Date(2008, 1, 1, 0, 30, 45, 125)
outputBlock.Text += String.Format("Date: {0:o}", date2) & vbCrLf
' Displays the following output:
'      Date: 2008-01-01T00:30:45.1250000

DateTime date2 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
outputBlock.Text += String.Format("Date: {0:o}",
                  date2) + "\n";
// Displays the following output:
//      Date: 2008-01-01T00:30:45.1250000

However, the "o" format specifier is intended less for displaying than for round-tripping or storing a DateTime value. You can also display milliseconds together with other date and time components by using a custom format string:

Dim date3 As New Date(2008, 1, 1, 0, 30, 45, 125)
outputBlock.Text += String.Format("Date with milliseconds: {0:MM/dd/yyy hh:mm:ss.fff}", _
                  date3) & vbCrLf
' Displays the following output:
'       Date with milliseconds: 01/01/2008 12:30:45.125

DateTime date3 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
outputBlock.Text += String.Format("Date with milliseconds: {0:MM/dd/yyy hh:mm:ss.fff}",
                  date3) + "\n";
// Displays the following output:
//       Date with milliseconds: 01/01/2008 12:30:45.125

Platform Notes

Silverlight for Windows Phone

System.DateTime.Now.Millisecond.ToString always returns zero on the Windows Phone Emulator.

Examples

The following example demonstrates the Millisecond property.

Dim moment As New System.DateTime(1999, 1, 13, 3, 57, 32, 11)

' Year gets 1999.
Dim year As Integer = moment.Year

' Month gets 1 (January).
Dim month As Integer = moment.Month

' Day gets 13.
Dim day As Integer = moment.Day

' Hour gets 3.
Dim hour As Integer = moment.Hour

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

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

' Millisecond gets 11.
Dim millisecond As Integer = moment.Millisecond

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