c# - What format is this time value in?

Question

I have a WMI query that specifies time in this format '20090219000000.000000+480'

Can someone tell me what format this is, and does .NET have any built-in functionality to work with it?

EDIT

This time value is from a sample query that I found. I don't know what time value was used to generate it. I just need to be able to convert a time value to this format.

EDIT 2

I found out this time is in CIM_DATETIME format.

Answer 1

As others have suggested the string is an example of DATETIME MOF data type. It is a fixed-length string and you can find details about its structure here. .Net uses System.Management namespace to access WMI and one of its classes is ManagementDateTimeConverter class which facilitates working with WMI datetime values.

Here is how you use all this:

var time_written = System.Management.ManagementDateTimeConverter.ToDateTime((string)result.GetPropertyValue("TimeWritten"));
