UTC Conversion Code

When working with Date/Time functions in the WMI environment, we need to remember that this data is given to us in UTC time. For example, the date 2/25/2008 10:07:08 PM is formatted as 20080225220708.000000-300. Below is a function that will translate this UTC time into the conventional formatting for date/time. The time being feed is the OS installation date/time for the client running the script.

strComputer = "."
Set objSWbemServices = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colOS = objSWbemServices.ExecQuery("SELECT * FROM Win32_OperatingSystem")
For Each objOS in colOS
Wscript.echo WMIDateStringtoDate(objOS.InstallDate)
Next

Function WMIDateStringToDate(dtmInstallDate)
WMIDateStringToDate = CDate(Mid(dtmInstallDate, 5, 2) & "/" & _
Mid(dtmInstallDate, 7, 2) & "/" & Left(dtmInstallDate, 4) _
& " " & Mid (dtmInstallDate, 9, 2) & ":" & _
Mid(dtmInstallDate, 11, 2) & ":" & Mid(dtmInstallDate, _
13, 2))
End Function

You may not have an error at all. Take a look at the drive mapping below. The red triangle is what threw us off. It is not an error. It is simply a color representation of the Replace option of the Action field in the properties of the drive mappings. Create action This give you a green triangle. The Create action creates a new mapped drive for users. Replace Action The Replace action gives you a red triangle. This action will delete and recreate mapped drives for users. The net result of the Replace action is to overwrite all existing settings associated with the mapped drive. If the drive mapping does not exist, then the Replace action creates a new drive mapping.
