[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Returns the Coordinated Universal Time (UTC) offset for the specified local time.

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

Public MustOverride Function GetUtcOffset ( _
	time As DateTime _
) As TimeSpan


Type: System..::..DateTime
A date and time value.

Return Value

Type: System..::..TimeSpan
The Coordinated Universal Time (UTC) offset from time.

This method returns the offset, or difference, between the time parameter and Coordinated Universal Time (UTC). That is:

time = UTC + offset

The method interprets the time zone of time based on its Kind property. If the value of the Kind property is DateTimeKind..::..Local or DateTimeKind.Unspecified, the method returns the offset of the local time zone. If the value of the Kind property is DateTimeKind..::..Utc, the method returns an offset equal to TimeSpan..::..Zero.

If the local time zone observes daylight saving time, GetUtcOffset applies the current adjustment rule to time when determining the offset of the local time zone. That is, the offset returned by GetUtcOffset reflects whether time falls in the time zone's standard time or its daylight saving time.
