The fact that you were unable to get they keyserver link right on your signature for a good while is an indication that you really do not know what you are doing when it comes to PGP, so I think it would be unlikely that you changed the time/date on your computer prior to creating your PGP key.

I wonder what exactly you were needing to encrypt less then 24 hours prior to dooglus blindly supporting you. It seems very fishy to me. I would not be surprised if it was something malicious
