"This module provides various functions to manipulate time values.\n\
\n\
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\
