I'm parsing a UTC Date string with SimpleDateFormat and it is parsed as the previous date. DateFormat df = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z"); This string "Fri, 06 Apr 2012 04:00:00 GMT" is being parsed as 4/5/2012. Why? Thanks. Below is example of date conversion... For your program, do changes accordingly and let me know what output you are getting. S
我使用SimpleDateFormat解析UTC日期字符串,并将其解析为上一个日期。 DateFormat df = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z"); 此字符串“Fri,06 Apr 2012 04:00:00 GMT”正在解析为2012年4月5日。 为什么? 谢谢。 以下是日期转换的示例... 对于你的程序,做相应的改变,让我知道你得到了什么输出。 String dateStr = "Thu Jan 19 2012 01:00 PM"; DateFormat readFormat = new SimpleDateForma
I have milliseconds in certain log file generated in server, I also know the locale from where the log file was generated, my problem is to convert milliseconds to date in specified format. The processing of that log is happening on server located in different time zone. While converting to "SimpleDateFormat" program is taking date of the machine as such formatted date do not represen
我在服务器生成的某些日志文件中有几毫秒,我也知道生成日志文件的语言环境,我的问题是将毫秒转换为指定格式的日期。 该日志的处理发生在位于不同时区的服务器上。 虽然转换为“SimpleDateFormat”程序正在取得机器的日期,因为这种格式化日期并不代表服务器的正确时间。 有没有办法处理这个优雅? long yourmilliseconds = 1322018752992l; //1322018752992-Nov 22, 2011 9:25:52 PM SimpleDateFormat sdf = new Si
I know that same kind of question has been asked for activity icon, but my question is little bit different. I just wanted to know whether we can set the application icon programmatically, I am not asking to change, I am just asking for setting it. I hope I am clear. <application android:icon="drawable resource"> </application> In the above example I am setting it in manifest fil
我知道同样的问题已经被要求提供活动图标,但是我的问题有点不同。 我只是想知道我们是否可以通过程序设置应用程序图标,我不是要求更改,而只是要求设置它。 我希望我很清楚。 <application android:icon="drawable resource"> </application> 在上面的例子中,我将它设置在清单文件中,但是可以通过java代码来设置它。 正如你可以在这里阅读http://developer.android.com/guide/topics/manifest/manifest-i
I have written a code to calculate number of days between dates in following way SimpleDateFormat date = new SimpleDateFormat("yyyy-MM-dd"); Date date1 = date.parse(startDate); Date date2 = date.parse(endDate); long difference = (date2.getTime()-date1.getTime())/(24*60*60*1000); My job is to find whether term between startDate and endDate is exactly one year. i am initially checking year ty
我已经编写了一个代码来按照以下方式计算日期之间的天数 SimpleDateFormat date = new SimpleDateFormat("yyyy-MM-dd"); Date date1 = date.parse(startDate); Date date2 = date.parse(endDate); long difference = (date2.getTime()-date1.getTime())/(24*60*60*1000); 我的工作是找出startDate和endDate之间的术语是否恰好是一年。 在计算日期之间的差异后,我最初检查年份类型(闰年/正常年份)。 如果不是闰年,那
After an upgrade of the OJDBC client from version 11.2.0 to 12.1.0, I experience a different behavior in binding a java.sql.Date object to a PreparedStatement. In the prepared statement, a host variable "f.plan_date = ?" should be binded with the value of a java.util.Date object, being an input obtained elsewhere in the code. The column data type in the Oracle table is "DATE&qu
将OJDBC客户端从版本11.2.0升级到12.1.0后,我遇到了将java.sql.Date对象绑定到PreparedStatement的不同行为。 在准备好的语句中,主变量“f.plan_date =?” 应该绑定一个java.util.Date对象的值,该对象是代码中其他位置获得的输入。 Oracle表中的列数据类型是“DATE”,只有日期部分应该被考虑 - 时间是不相关的。 我按照以下方式在java.sql.Date对象中转换了java.util.Date对象: statementRegisterJobs.setDate(3, new ja
i have made a function to convert from one time zone to another by using joda time but the function is not accepting the date i have passed the following parameters to this function "Asia/Kolkata" , "UTC" , "12-Dec-2014 12:30" . It is throwing the following exception: Exception in thread "main" java.lang.IllegalArgumentException: Invalid format: "12-Dec-2014 12:3
我已经做了一个功能,通过使用乔达时间从一个时区转换到另一个时区,但功能不接受日期 我已将以下参数传递给此功能"Asia/Kolkata" , "UTC" , "12-Dec-2014 12:30" 。 它抛出以下异常: Exception in thread "main" java.lang.IllegalArgumentException: Invalid format: "12-Dec-2014 12:32" is malformed at "-Dec-2014 12:32" at org.joda.time.format.DateTimeFormatter.parseMillis(Date
The javdoc for LocalDate#toDateMidnight reads as follows: As from v1.5, you are recommended to avoid DateMidnight and use toDateTimeAtStartOfDay() instead because of the exception detailed below. This method will throw an exception if the default time zone switches to Daylight Savings Time at midnight and this LocalDate represents that switchover date. The problem is that there is no such ti
LocalDate#toDateMidnight内容如下: 从v1.5开始,建议您避免使用DateMidnight,并使用toDateTimeAtStartOfDay()代替,因为下面详述了这个例外。 如果默认时区在午夜切换为夏令时并且此LocalDate表示切换日期,则此方法将引发异常。 问题在于,没有必要的日期是午夜,因此抛出异常。 事实上,某些时区中不存在午夜似乎足以避免完全使用DateMidnight (假设您的代码未使用已知不具有此DST情况的固定时区,并且将永远不需
Joda Time's LocalDate describe itself as: LocalDate is an immutable datetime class representing a date without a time zone. Yet there is a LocalDate(Object instant, DateTimeZone zone) constructor that accepts time zone. If the object is time zone-less, what's the purpose of the time zone constructor? The constructor JavaDocs states: Constructs an instance from an Object that repr
乔达时间的LocalDate描述为: LocalDate是一个不可变的日期时间类,代表没有时区的日期。 然而,还有一个接受时区的LocalDate(Object instant, DateTimeZone zone)构造函数。 如果对象是无时区的,那么时区构造函数的目的是什么? 构造函数JavaDocs指出: 从表示日期时间的Object构造一个实例,强制时区到指定的时间。 我不知道“强制指定的时区”是什么意思,因为对象是无时区的。 也许它在内部转换为UTC,然后删除时
I'm wrestling with the issue of time zones across SQL, jdbc, JVM and linux. I can see that the class I need to hand to / get from jdbc is java.sql.date. So I read the documentation, and can't make ANYTHING of it. As I understand it, both java.util.Data and java.sql.date hold a number of milliseconds since the epoch. When I look at the definition for the constructor for java.sql.dat
我正在处理跨SQL,jdbc,JVM和linux的时区问题。 我可以看到我需要从/从jdbc获取的类是java.sql.date。 所以我读了文档,不能做任何事情。 据我所知,java.util.Data和java.sql.date都持有自纪元以来的毫秒数。 当我看到java.sql.date构造函数的定义时,它说 “使用给定的毫秒时间值构造一个Date对象,如果给定的毫秒值包含时间信息,则驱动程序会将时间组件设置为默认时区(运行应用程序的Java虚拟机的时区)中的时间对
java.util.Date vs java.sql.Date :何时使用哪些和为什么? Congratulations, you've hit my favorite pet peeve with JDBC: Date class handling. Basically databases usually support at least three forms of datetime fields which are date, time and timestamp. Each of these have a corresponding class in JDBC and each of them extend java.util.Date . Quick semantics of each of these three are the fo
java.util.Date vs java.sql.Date :何时使用哪些和为什么? 恭喜,你已经用JDBC打了我最喜欢的宠物:日期类处理。 基本上数据库通常支持至少三种日期时间字段,它们是日期,时间和时间戳。 它们中的每一个在JDBC中都有相应的类,并且每个类都扩展了java.util.Date 。 这三者中每一个的快速语义如下: java.sql.Date对应于SQL DATE,这意味着它存储年,月和日,而小时,分钟,秒和毫秒被忽略。 另外sql.Date不绑定到时区
