ManagementDateTimeConverter.ToDmtfDateTime Method (DateTime)


Converts a given DateTime to DMTF datetime format.

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

public static string ToDmtfDateTime(
	DateTime date


Type: System.DateTime

A DateTime representing the datetime to be converted to DMTF datetime.

Return Value

Type: System.String

A string that represents the DMTF datetime for the given DateTime.

Date and time in WMI is represented in DMTF datetime format. This format is explained in WMI SDK documentation. The DMTF datetime string represented will be with respect to the UTC offset of the current time zone. The lowest precision in DMTF is microseconds; in DateTime, the lowest precision is Ticks, which are 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 DateTime to DMTF datetime format.

using System;
using System.Management;

// The sample below demonstrates the various conversions
// that can be done using ManagementDateTimeConverter class    
class Sample_ManagementDateTimeConverterClass
    public static int Main(string[] args) 
        string dmtfDate = "20020408141835.999999-420";
        string dmtfTimeInterval = "00000010122532:123456:000";

        // Converting DMTF datetime to System.DateTime
        DateTime dt = 

        // Converting System.DateTime to DMTF datetime
        string dmtfDateTime = 

        // Converting DMTF time interval to System.TimeSpan
        System.TimeSpan tsRet = 

        //Converting System.TimeSpan to DMTF time interval format
        System.TimeSpan ts = 
            new System.TimeSpan(10,12,25,32,456);
        string dmtfTimeInt  = 

        return 0;
