Windows Phone SDK 8.0 Failed to Install - A required certificate is not within its validity period [SOLVED]

Story:
I want to install Windows Phone SDK 8.0

Problem:
Windows Software Development Kit Tools for Windows Store
A required certificate is not within its validity period when verifiying against the current system clock or the timestamp in the signed file.

Microsoft Visual Studio 2012 Shell (Minimum) Interop Assem User cancelled installation.

Real problem: All "google" answer redirect me to some SQL Server installation stuff.
Buttomline: No good answer.

Analisys:
Certificate? Timestamp? Period? It must have something to do with woman Current System Clock.

Solution:
Change your current time to 2012.

It works!

Man, I can't believe it..
