New submission from ingo janssen <ingoo...@gmail.com>: Short: make the DateTime class and related also accept 24 for the hour instead of stopping at 23:59:59.
from the python doc: "class datetime.datetime(year, month, day[, hour[, minute[, second[, microsecond[, tzinfo]]]]]) The year, month and day arguments are required. tzinfo may be None, or an instance of a tzinfo subclass. The remaining arguments may be ints or longs, in the following ranges: [...] 0 <= hour < 24 [...] If an argument outside those ranges is given, ValueError is raised." from http://en.wikipedia.org/wiki/ISO_8601 : "ISO 8601 uses the 24-hour clock system. The basic format is [hh][mm][ss] and the extended format is [hh]:[mm]:[ss]. * [hh] refers to a zero-padded hour between 00 and 24 (where 24 is only used to notate midnight at the end of a calendar day). [...] Midnight is a special case and can be referred to as both "00:00" and "24:00". The notation "00:00" is used at the beginning of a calendar day and is the more frequently used. At the end of a day use "24:00". Note that "2007-04-05T24:00" is the same instant as "2007-04-06T00:00" (see Combined date and time representations below)." The use of 24:00 is very comfortable when using hourly datasets, the first set of a day is saved under 1:00, the fifth (4:00 to 5:00) under 5:00 and the last (23:00 - 24:00) under 24:00. No need to suddenly use 23:59:59 or 0:00 the next day. Actually in another part of Python SQLlite's date and time functions accept and outputs the 24:00. Adding some Python to an existing database made me aware of the problem. ---------- messages: 121230 nosy: ingo.janssen priority: normal severity: normal status: open title: 24:00 Hour in DateTime type: feature request versions: Python 2.5, Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10427> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
