问题 Consider the following date string 2012-10-01 01:02:03.004+0500 This is recognized in Java using the following SimpleDateFormat pattern: yyyy-MM-dd HH:mm:ss.SSSZ If, however, the timezone information above is truncated to 2 digits, i.e. like 2012-10-01 01:02:03.004+05 the date string does not comply to any valid format, so there is no SimpleDateFormat pattern that could be used in order to correctly parse it. Is there any workaround for parsing the truncated timezone correctly without string

问题 With the following in my rails_defaults.rb: Date::DATE_FORMATS[:default] = '%m/%d/%Y' Time::DATE_FORMATS[:default]= '%m/%d/%Y %H:%M:%S' Why do the following results differ: ruby-1.9.2-p180 :005 > MyModel.find(2).to_json(:only => :start_date) => "{\"start_date\":\"2012-02-03\"}" ruby-1.9.2-p180 :006 > MyModel.find(2).start_date.to_s => "02/03/2012" And more importantly, how do I get to_json to use %m/%d/%Y ? 回答1: Because the standard JSON format for a date is %Y-%m-%d and there's no way to

问题 My team is looking to switch from Joda time to java.time , but we're seeing different behavior in formatting using the same pattern. The issue arises when we're using the week-of-week-year w symbol: final String dateString = "2016-01-04 00:00:00"; final String inputPattern = "yyyy-MM-dd HH:mm:ss"; // parse the input string using Joda final org.joda.time.format.DateTimeFormatter jodaInputFormatter = org.joda.time.format.DateTimeFormat.forPattern(inputPattern); final org.joda.time.DateTime

问题 '2009-12 Dec' should be converted to '31-DEC-2009' '2010-09 Sep' should be converted to '30-SEP-2010' '2010-02 Feb' should be converted to '28-FEB-2010' '2008-02 Feb' should be converted to '29-FEB-2008' The values 2009-12 Dec , 2008-02 Feb will be displayed to the User in a drop down.

问题 I am trying to import a column of dates from a spreadsheet in Excel 2003 into SQL Server 2005 using SSIS. I am in the UK so want dates formatted as dd/MM/yyyy. Unfortunately, the column in the spreadsheet contains a mixture of dates stored as strings in dd/MM/yyyy (with Excel 'General' formatting) as well as dates using Excel 'Date' formatting dd/MM/yyyy (with locale 'English (United Kingdom)'). This is just the way it is and I can't expect the users to be able to sort this out themselves.

问题 I want to print a time without seconds in the default format for the locale. So I get the formatter with getTimeInstance() or getTimeInstance(int style) . But even when I use a SHORT style it will contain the seconds part of the time as well. Is there any way (apart from creating my own format, which then would not be the locale default and manually maintained) I can grab the default and split off the seconds ? Thanks Roman 回答1: DateFormat.getTimeInstance( DateFormat.SHORT ) works perfectly

问题 I'm using a DateTime SWT component, and it has an American format when displayed (mm/dd/yyyy). Is there any way to change the format to dd/mm/yyyy ? 回答1: DateTime uses the OS specific user preferences to format the date. (On Windows these are the Regional and Language Options in the system settings). A possible workaround is described here (scroll down to the latest two entries). But I haven't tried this myself. 回答2: You need to set the locale to change the date format, e.g. to Italy who use

问题 I'm trying to format a date for a given locale new Locale("mk", "MK") . The locale is valid, it returns the country name and language properly. I want to use custom string, in my case "E, kk:mm" or "EEEE, kk:mm". I want the output to be "сабота, 12:00", but what I get is "7, 12:00". This is how I use it and I tried many ways, but they all seem to behave the same. SimpleDateFormat sdf = new SimpleDateFormat("EEEE, kk:mm", new Locale("mk", "MK)); sdf.format(new Date()); // output: 7, 12:30
