      6 This module provides various functions to manipulate time values.
      7 
      8 There are two standard representations of time.  One is the number
      9 of seconds since the Epoch, in UTC (a.k.a. GMT).  It may be an integer
     10 or a floating point number (to represent fractions of seconds).
     11 The Epoch is system-defined; on Unix, it is generally January 1st, 1970.
     12 The actual value can be retrieved by calling gmtime(0).
     13 
     14 The other representation is a tuple of 9 integers giving local time.
     15 The tuple items are:
     16   year (including century, e.g. 1998)
     17   month (1-12)
     18   day (1-31)
     19   hours (0-23)
     20   minutes (0-59)
     21   seconds (0-59)
     22   weekday (0-6, Monday is 0)
     23   Julian day (day in the year, 1-366)
     24   DST (Daylight Savings Time) flag (-1, 0 or 1)
     25 If the DST flag is 0, the time is given in the regular time zone;
     26 if it is 1, the time is given in the DST time zone;
     27 if it is -1, mktime() should guess based on the date and time.
     28 
     29 Variables:
     30 
     31 timezone -- difference in seconds between UTC and local standard time
     32 altzone -- difference in  seconds between UTC and local DST time
     33 daylight -- whether local time should reflect DST
     34 tzname -- tuple of (standard time zone name, DST time zone name)
     35 
     36 Functions:
     37 
     38 time() -- return current time in seconds since the Epoch as a float
     39 clock() -- return CPU time since process start as a float
     40 sleep() -- delay for a number of seconds given as a float
     41 gmtime() -- convert seconds since Epoch to UTC tuple
     42 localtime() -- convert seconds since Epoch to local time tuple
     43 asctime() -- convert time tuple to string
     44 ctime() -- convert time in seconds to string
     45 mktime() -- convert local time tuple to seconds since Epoch
     46 strftime() -- convert time tuple to string according to format specification
     47 strptime() -- parse string to time tuple according to format specification
     48 tzset() -- change the local timezone
