ManagementDateTimeConverter.ToDmtfTimeInterval Method

Converts a given TimeSpan to DMTF time interval.

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

'Declaration
Public Shared Function ToDmtfTimeInterval ( _
	timespan As TimeSpan _
) As String

Parameters

timespan
Type: System.TimeSpan

A TimeSpan representing the datetime to be converted to DMTF time interval.

Return Value

Type: System.String
A string that represents the DMTF time interval for the given TimeSpan.

Time interval in WMI is represented in DMTF datetime format. This format is explained in WMI SDK documentation. The lowest precision in DMTF is microseconds; in TimeSpan, the lowest precision is Ticks, which is equivalent to 100 nanoseconds. During conversion, Ticks are converted to microseconds and rounded off to the nearest microsecond.

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.

The following example converts a given TimeSpan to DMTF time interval.
