+There are two standard representations of time.  One is the number\n\
+of seconds since the Epoch, in UTC (a.k.a. GMT).  It may be an integer\n\
+or a floating point number (to represent fractions of seconds).\n\
+The Epoch is system-defined; on Unix, it is generally January 1st, 1970.\n\
+The actual value can be retrieved by calling gmtime(0).\n\
+\n\
+The other representation is a tuple of 9 integers giving local time.\n\
+The tuple items are:\n\
+  year (four digits, e.g. 1998)\n\
+  month (1-12)\n\
+  day (1-31)\n\
+  hours (0-23)\n\
+  minutes (0-59)\n\
+  seconds (0-61, to allow for leap seconds)\n\
+  weekday (0-6, Monday is 0)\n\
+  Julian day (day in the year, 1-366)\n\
+  DST (Daylight Savings Time) flag (-1, 0 or 1)\n\
+If the DST flag is 0, the time is given in the regular time zone;\n\
+if it is 1, the time is given in the DST time zone;\n\
+if it is -1, mktime() should guess based on the date and time.\n\
+\n\
+Variables:\n\
+\n\
+timezone -- difference in seconds between UTC and local standard time\n\
+altzone -- difference in  seconds between UTC and local DST time\n\
+daylight -- whether local time should reflect DST\n\
+tzname -- tuple of (standard time zone name, DST time zone name)\n\
+\n\
+Functions:\n\
+\n\
+time() -- return current time in seconds since the Epoch as a float\n\
+clock() -- return CPU time since process start as a float\n\
+sleep() -- delay for a number of seconds given as a float\n\
+gmtime() -- convert seconds since Epoch to UTC tuple\n\
+localtime() -- convert seconds since Epoch to local time tuple\n\
+asctime() -- convert time tuple to string\n\
+ctime() -- convert time in seconds to string\n\
+mktime() -- convert local time tuple to seconds since Epoch\n\
+strftime() -- convert time tuple to string according to format specification\n\
+strptime() -- parse string to time tuple according to format specification\n\
