| 725 | \n\ |
| 726 | There are two standard representations of time. One is the number\n\ |
| 727 | of seconds since the Epoch, in UTC (a.k.a. GMT). It may be an integer\n\ |
| 728 | or a floating point number (to represent fractions of seconds).\n\ |
| 729 | The Epoch is system-defined; on Unix, it is generally January 1st, 1970.\n\ |
| 730 | The actual value can be retrieved by calling gmtime(0).\n\ |
| 731 | \n\ |
| 732 | The other representation is a tuple of 9 integers giving local time.\n\ |
| 733 | The tuple items are:\n\ |
| 734 | year (four digits, e.g. 1998)\n\ |
| 735 | month (1-12)\n\ |
| 736 | day (1-31)\n\ |
| 737 | hours (0-23)\n\ |
| 738 | minutes (0-59)\n\ |
| 739 | seconds (0-59)\n\ |
| 740 | weekday (0-6, Monday is 0)\n\ |
| 741 | Julian day (day in the year, 1-366)\n\ |
| 742 | DST (Daylight Savings Time) flag (-1, 0 or 1)\n\ |
| 743 | If the DST flag is 0, the time is given in the regular time zone;\n\ |
| 744 | if it is 1, the time is given in the DST time zone;\n\ |
| 745 | if it is -1, mktime() should guess based on the date and time.\n\ |
| 746 | \n\ |
| 747 | Variables:\n\ |
| 748 | \n\ |
| 749 | timezone -- difference in seconds between UTC and local standard time\n\ |
| 750 | altzone -- difference in seconds between UTC and local DST time\n\ |
| 751 | daylight -- whether local time should reflect DST\n\ |
| 752 | tzname -- tuple of (standard time zone name, DST time zone name)\n\ |
| 753 | \n\ |
| 754 | Functions:\n\ |
| 755 | \n\ |
| 756 | time() -- return current time in seconds since the Epoch as a float\n\ |
| 757 | clock() -- return CPU time since process start as a float\n\ |
| 758 | sleep() -- delay for a number of seconds given as a float\n\ |
| 759 | gmtime() -- convert seconds since Epoch to UTC tuple\n\ |
| 760 | localtime() -- convert seconds since Epoch to local time tuple\n\ |
| 761 | asctime() -- convert time tuple to string\n\ |
| 762 | ctime() -- convert time in seconds to string\n\ |
| 763 | mktime() -- convert local time tuple to seconds since Epoch\n\ |
| 764 | strftime() -- convert time tuple to string according to format specification\n\ |
| 765 | strptime() -- parse string to time tuple according to format specification\n\ |
| 766 | tzset() -- change the local timezone"); |
