Windows 10 WMI Win32_NetworkAdapterConfiguration not consistent

[KonstantinosP1]

Hello,
recently i am experimenting with the WMI.
I am running windows 10 home 64 bit version and i discovered that when i am quering Win32_NetworkAdapterConfiguration, variables DHCPLeaseExpires and DHCPLeaseObtained have not right values.
I have tried to run the same command on windows 8.1 and on windows server 2012r but the results were the expected ones.

The command that i run in Powershell is: "get-wmiobject win32_networkadapterconfiguration | select caption,description, DHCPLeaseExpires, DHCPLeaseObtained"

The results are:

DHCPLeaseExpires DHCPLeaseObtained
---------------- -----------------

19700102110845.000000+120 19700102103845.000000+120
19700102110845.000000+120 19700102103845.000000+120
19700102113849.000000+120 19700102103849.000000+120

Nevertheless when I am running the command "ipconfig /all" I get the correct values

For example:

Lease Obtained. . . . . . . . . . : Τρίτη, 20 Μαρτίου 2018 11:38:36 μμ
Lease Expires . . . . . . . . . . : Τετάρτη, 21 Μαρτίου 2018 12:23:36 πμ

Why in the first occasion the year is 1970 instead of 2018?
