DateTimeOffset.ToUniversalTime Method

Converts the current DateTimeOffset object to a DateTimeOffset value that represents the Coordinated Universal Time (UTC).

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

'Declaration
Public Function ToUniversalTime As DateTimeOffset

Return Value

Type: System.DateTimeOffset
An object that represents the date and time of the current DateTimeOffset object converted to Coordinated Universal Time (UTC).

This method returns a DateTimeOffset object whose Offset property is set to zero.

Both the value of the current DateTimeOffset object and the value of the DateTimeOffset object returned by the method call represent the same point in time. That is, if both are passed to the DateTimeOffset.Equals(DateTimeOffset, DateTimeOffset) method, the method will return true.

The following example calls the ToUniversalTime method to convert a local time and several other times to Coordinated Universal Time (UTC).


Dim localTime, otherTime, universalTime As DateTimeOffset

' Define local time in local time zone
localTime = New DateTimeOffset(#6/15/2007 12:00:00 PM#)
outputBlock.Text += String.Format("Local time: {0}", localTime) & vbCrLf
outputBlock.Text &= vbCrLf

' Convert local time to offset 0 and assign to otherTime
otherTime = localTime.ToOffset(TimeSpan.Zero)
outputBlock.Text += String.Format("Other time: {0}", otherTime) & vbCrLf
outputBlock.Text += String.Format("{0} = {1}: {2}", _
                  localTime, otherTime, _
                  localTime.Equals(otherTime)) + vbCrLf
outputBlock.Text += String.Format("{0} exactly equals {1}: {2}", _
                  localTime, otherTime, _
                  localTime.EqualsExact(otherTime)) + vbCrLf
outputBlock.Text &= vbCrLf

' Convert other time to UTC
universalTime = localTime.ToUniversalTime()
outputBlock.Text += String.Format("Universal time: {0}", universalTime) & vbCrLf
outputBlock.Text += String.Format("{0} = {1}: {2}", _
                  otherTime, universalTime, _
                  universalTime.Equals(otherTime)) + vbCrLf
outputBlock.Text += String.Format("{0} exactly equals {1}: {2}", _
                  otherTime, universalTime, _
                  universalTime.EqualsExact(otherTime)) + vbCrLf
outputBlock.Text &= vbCrLf
' The example produces the following output:
'    Local time: 6/15/2007 12:00:00 PM -07:00
'    
'    Other time: 6/15/2007 7:00:00 PM +00:00
'    6/15/2007 12:00:00 PM -07:00 = 6/15/2007 7:00:00 PM +00:00: True
'    6/15/2007 12:00:00 PM -07:00 exactly equals 6/15/2007 7:00:00 PM +00:00: False
'    
'    Universal time: 6/15/2007 7:00:00 PM +00:00
'    6/15/2007 7:00:00 PM +00:00 = 6/15/2007 7:00:00 PM +00:00: True
'    6/15/2007 7:00:00 PM +00:00 exactly equals 6/15/2007 7:00:00 PM +00:00: True
