/** Proof that Java is retarded. Instead of an easy gmtime() method, I have to use
the deprecated Date class; I absolutely refuse to use java.util.Calendar with all its
get(Calendar.CONSTANT) and set(Calendar.CONSTANT) methods. C uses gmtime(), Perl uses
gmtime(), Ruby uses gmtime(), Python uses gmtime(), even Lua has os.date("%z")! **/
