strptime

I tried parsing using Date.parse("28-May-10").to_s Returns 0010-5-28 (which is 2000 years off!) How can I get ruby to interpret the two digit year properly. There are plenty of string to date conversion tricks out there on google but most handle digit months as opposed to "May". I prefer Date.strptime for this task: require 'date' puts Date.strptime("28-May-10", "%d-%b-%y") #2010-05-28 来源： https://stackoverflow.com/questions/9727898/parsing-string-dates-in-ruby-such-as-28-may-10

I am trying to simply create a datetime object from the following date: 'Fri Mar 11 15:59:57 EST 2016' using the format: '%a %b %d %H:%M:%S %Z %Y'. Here's the code. from datetime import datetime date = datetime.strptime('Fri Mar 11 15:59:57 EST 2016', '%a %b %d %H:%M:%S %Z %Y') However, this results in a ValueError as shown below. ValueError: time data 'Fri Mar 11 15:59:57 EST 2016' does not match format '%a %b %d %H:%M:%S %Z %Y' Maybe I am missing something obviously wrong with my format string, but I have checked it over and over. Any help would be greatly appreciated, thanks. Edit to

I am trying to extract out the time from a character string in R and can't stop getting NA as a result. I have tried numerous variations of the regular expression tags, but can't seem to get around this simple problem. Any help/clarifications are appreciated. Here is my code for an example: > x [1] "2/7/2013 7:43" > class(x) [1] "character" > z <- strptime(x, "%H:%M") > z [1] NA R doesn't know that your string is a datetime. So make it one first: y <- strptime(x, format='%m/%d/%Y %H:%M') If you were trying to get just the date, you could do: strptime(x, '%m/%d/%Y') Because strptime discards

I want to parse dates like these into a datetime object: December 12th, 2008 January 1st, 2009 The following will work for the first date: datetime.strptime("December 12th, 2008", "%B %dth, %Y") but will fail for the second because of the suffix to the day number ('st'). So, is there an undocumented wildcard character in strptime? Or a better approach altogether? Try using the dateutil.parser module. import dateutil.parser date1 = dateutil.parser.parse("December 12th, 2008") date2 = dateutil.parser.parse("January 1st, 2009") Additional documentation can be found here: http://labix.org/python

I am trying to convert a unicode object to a datetime object. I read through the documentation: http://docs.python.org/2/library/time.html#time.strptime and tried datetime.strptime(date_posted, '%Y-%m-%dT%H:%M:%SZ') but I get the error message ValueError: time data '2014-01-15T01:35:30.314Z' does not match format '%Y-%m-%dT%H:%M:%SZ' Any feedback on what is the proper format? I appreciate the time and expertise. You can parse the microseconds: from datetime import datetime date_posted = '2014-01-15T01:35:30.314Z' datetime.strptime(date_posted, '%Y-%m-%dT%H:%M:%S.%fZ') One option is to let
