776 The Epoch is system-defined; on Unix, it is generally January 1st, 1970.\n\
777 The actual value can be retrieved by calling gmtime(0).\n\

781 year (four digits, e.g. 1998)\n\
787 weekday (0-6, Monday is 0)\n\
788 Julian day (day in the year, 1-366)\n\

791 if it is 1, the time is given in the DST time zone;\n\
792 if it is -1, mktime() should guess based on the date and time.\n\
796 timezone -- difference in seconds between UTC and local standard time\n\
797 altzone -- difference in seconds between UTC and local DST time\n\
798 daylight -- whether local time should reflect DST\n\
799 tzname -- tuple of (standard time zone name, DST time zone name)\n\
803 time() -- return current time in seconds since the Epoch as a float\n\
804 clock() -- return CPU time since process start as a float\n\
805 sleep() -- delay for a number of seconds given as a float\n\
