Python datetime.strftime() delegates to C strftime() function that is platform-dependent: The full set of format codes supported varies across platforms, because Python calls the platform C library’s strftime() function, and platform variations are common. To see the full set of format codes supported on your platform, consult the strftime(3) documentation. Glibc notes for strftime(3): – … Read more
Unless you’re using Rails, add this ordinalize method (code shamelessly lifted from the Rails source) to the Fixnum class class Fixnum def ordinalize if (11..13).include?(self % 100) “#{self}th” else case self % 10 when 1; “#{self}st” when 2; “#{self}nd” when 3; “#{self}rd” else “#{self}th” end end end end Then format your date like this: > … Read more
I assume you are using ISO 8601 week numbers, and want the first day of a ISO 8601 week so that e.g. Week 1 of 2011 returns January 3 2011. strtotime can do this out of the box using the {YYYY}W{WW} format: echo date(“Y-m-d”, strtotime(“2011W01”)); // 2011-01-03 Note that the week number needs to be … Read more
The example given by Rob is great, but isn’t threadsafe. Here’s a version that works with threads: import locale import threading from datetime import datetime from contextlib import contextmanager LOCALE_LOCK = threading.Lock() @contextmanager def setlocale(name): with LOCALE_LOCK: saved = locale.setlocale(locale.LC_ALL) try: yield locale.setlocale(locale.LC_ALL, name) finally: locale.setlocale(locale.LC_ALL, saved) # Let’s set a non-US locale locale.setlocale(locale.LC_ALL, ‘de_DE.UTF-8’) … Read more
strftime doesn’t allow you to format a date with a suffix. Here’s a way to get the correct suffix: if 4 <= day <= 20 or 24 <= day <= 30: suffix = “th” else: suffix = [“st”, “nd”, “rd”][day % 10 – 1] found here Update: Combining a more compact solution based on Jochen’s … Read more
You can use datetime’s strftime function to get this. The problem is that time’s strftime accepts a timetuple that does not carry microsecond information. from datetime import datetime datetime.now().strftime(“%H:%M:%S.%f”) Should do the trick!
The T doesn’t really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time. The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC). Both characters are just static letters in … Read more
In bash (>=4.2) it is preferable to use printf’s built-in date formatter (part of bash) rather than the external date (usually GNU date). As such: # put current date as yyyy-mm-dd in $date # -1 -> explicit current date, bash >=4.3 defaults to current time if not provided # -2 -> start time for shell … Read more
Actually I had the same problem and I realized that, if you add a hyphen between the % and the letter, you can remove the leading zero. For example %Y/%-m/%-d. This only works on Unix (Linux, OS X), not Windows (including Cygwin). On Windows, you would use #, e.g. %Y/%#m/%#d.
If you want to convert a python datetime to seconds since epoch you could do it explicitly: >>> (datetime.datetime(2012,04,01,0,0) – datetime.datetime(1970,1,1)).total_seconds() 1333238400.0 In Python 3.3+ you can use timestamp() instead: >>> datetime.datetime(2012,4,1,0,0).timestamp() 1333234800.0 Why you should not use datetime.strftime(‘%s’) Python doesn’t actually support %s as an argument to strftime (if you check at http://docs.python.org/library/datetime.html#strftime-and-strptime-behavior it’s … Read more
