ManagementDateTimeConverter.ToDmtfTimeInterval Method

Converts a given TimeSpan to DMTF time interval.

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

public static string ToDmtfTimeInterval (
	TimeSpan timespan
)
public static String ToDmtfTimeInterval (
	TimeSpan timespan
)
public static function ToDmtfTimeInterval (
	timespan : TimeSpan
) : String

Parameters

timespan

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

Return Value

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.

.NET Framework Security

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.

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 = 
            ManagementDateTimeConverter.ToDateTime(dmtfDate);
   
        // Converting System.DateTime to DMTF datetime
        string dmtfDateTime = 
            ManagementDateTimeConverter.ToDmtfDateTime(DateTime.Now);

        // Converting DMTF time interval to System.TimeSpan
        System.TimeSpan tsRet = 
            ManagementDateTimeConverter.ToTimeSpan(dmtfTimeInterval);

        //Converting System.TimeSpan to DMTF time interval format
        System.TimeSpan ts = 
            new System.TimeSpan(10,12,25,32,456);
        string dmtfTimeInt  = 
            ManagementDateTimeConverter.ToDmtfTimeInterval(ts);
        
        return 0;
    }
}
