Early in the 20th century the US railroads gave us Standard time.
Sometime during WWII the US Army gave us Zulu time, now known as GMT or perhaps other acronyms that include atomic time and leap seconds.
The Federal Aviation Agency insisted that flight plans be filed in Zulu time sometime before I got my license in 1967.
Astronomers, I am one, have been using Julian date/time since Hector was a pup.
UNIX has been using Zulu time when it time stamps a file on a disk since UNIX existed.
Apple changed from local time for a time stamp on a file to Zulu sometime after OS 7 but my SE/30 server running 7.5 still seems to get confused with my Linux box that communicates with ftp.
Ham radio learned long ago that Zulu time was the way to go.
The very idea that modern Computer Science (capitalized to indicate it's acceptance as a science) even tries to do anything else but keep Zulu time is just silly. The proper solution is for computer science to declare that it knows ONLY Zulu and that users had better decide that they accept it.
It's not really much different than what the railroads did with standard time while there really were people deciding when noon occurred with a sundial and an analemma <http://www.analemma.com/>.
Government schemes to somehow increase the ratio of sunlight to darkness in northern latitudes should be treated to what they deserve. Vote them out.
