There are many systems for which the Google fix would not work in the current state of technology unless implemented by EVERYBODY synchronously. At least everybody who depends on precise time like banking and financial systems, let alone the physicists and many others...
Keep in mind that this system drives you to having pretty bad time for the better part of a whole day, on purpose... I realize that when the alternative is a system crash, it may sound tempting, but it really is not a fix, a bandage at most. We have a term for that in French: "emplâtre sur une jambe de bois", cast on a wooden leg.
