I really have second thoughts on this issue, you dont care what the machine time is you care the server time.. The next issue is that there is not a single article about ATM's failing in San Deigo in a mass scale in 2007.. That would have been big news..
The guy seems to be real, but the article is a little more fiction.. I would never use the terminals time, it is the time the termial talks to the base system that is most important which is where when the phones are down then the ATM's fail.. The codes are not based on GPS they have highly specific clocks, which is the same technology in the RSA keyrings you can buy. GPS is alot more expensive than a proper crystal..http://www.rsa.com/node.aspx?id=1311 He also mentioned the ATMS talked wirelessly, SHIT the Military had blocked that for the prupose of the exersice all wireless communication.. He just went to far in his assumptions that GPS caused the ATM's to fail.. Your cell phone also is not going to fail in the US because of lack of GPS..
