Mis-dated Google+ Posts - Why?

Google did not exist in 1969, and neither did personal computers. Yet some of my posts at Google+ are dated December 31, 1969. I don't have access to state secrets, and it is certainly no secret that the government shutdown is over. Therefore, I must assume that the post is mis-dated as some kind of code to set certain of my posts aside like those that got special coding at Twitter a few years ago and at Care2. If there is some acceptable reason for my post to be mis-dated, please inform me. Thank you.

Hello. This is probably my cyberstalkers' doing, but I am prevented from signing in at Webmaster when in my JusticeGagged blog, and possibly from my other blogs as well:

and others. I was already signed in at my blog when I elected to check my blog's status at Webmaster, and I was given a field to sign in. I entered my password twice, but the response was that my password was incorrect. First, I don't believe I should be asked for my password when I am already signed in at Google. Secondly, why was my password not accepted?

Thank you for looking into this problem for me. I get Internet through AT&T, and there is an AT&T van parked in a driveway across the street from my home 24/7. I do not know if the van is a part of my problem, which began years before I became an AT&T customer. I feel certain that stalkers go online with me from my initial sign-on to the Internet and travel with me from one Internet site to another to censor me. However, in some instances, they access my account at various major Internet companies, such as Facebook, which sends me emails with messages such as this:
