Alexander Belopolsky added the comment: I would like to add my +1 to this issue. I suggest adding something like this: """ Commonly used format codes: %Y Year with century as a decimal number. %m Month as a decimal number [01,12]. %d Day of the month as a decimal number [01,31]. %H Hour (24-hour clock) as a decimal number [00,23]. %M Minute as a decimal number [00,59]. %S Second as a decimal number [00,61]. %z Time zone offset from UTC. %a Locale’s abbreviated weekday name. %A Locale’s full weekday name. %b Locale’s abbreviated month name. %B Locale’s full month name. %c Locale’s appropriate date and time representation. Other codes may be available on your platform. See documentation for the C library strftime function. """ This is a subjective selection in a subjective order of importance, so some bikesheding is welcome. My choice was motivated by the assumption that most commonly used are the codes required to form RFC 3339 timestamps. I deliberately omitted deprecated %y code and the %Z code that produces non-standardized TZ names. I can be persuaded to add 12 hour clock codes. ---------- assignee: docs@python -> belopolsky _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue9650> _______________________________________
