本文整理了Java中net.fortuna.ical4j.model.Date类的一些代码示例，展示了Date类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Date类的具体详情如下：
包路径：net.fortuna.ical4j.model.Date
类名称：Date

Date介绍

[英]A representation of the DATE object defined in RFC5445.

NOTE: iCal4j calculates the timezone of Date objects by default. In the iCalendar specification a DATE object doesn't really have a timezone associated with it, but in the ical4j implementation it does (as it is based on a java.util.Date object). An unfortunate side effect of this is that a Date object can be affected by daylight savings rules for the associated timezone. So currently ical4j offers two approaches to setting the timezone:

  1. Use UTC time (no DST rules, but depending on how the Date is constructed it may change the displayed value
  2. Use local timezone (in rare cases the DST rules may affect the displayed value).

By default option 1 is used, but you can override this with the following flag in the ical4j.properties file: net.fortuna.ical4j.timezone.date.floating=true

Alternatively you can avoid using the constructor that accepts a java.util.Date object, and instead provide a date string value. This should always display the correct value, however when the local timezone is used any calculations (recurrences, etc.) may still be affect by DST rules.

Extract from RFC5545:

3.3.4.  Date 
Value Name:  DATE 
Purpose:  This value type is used to identify values that contain a 
calendar date. 
Format Definition:  This value type is defined by the following 
notation: 
date               = date-value 
date-value         = date-fullyear date-month date-mday 
date-fullyear      = 4DIGIT 
date-month         = 2DIGIT        ;01-12 
date-mday          = 2DIGIT        ;01-28, 01-29, 01-30, 01-31 
;based on month/year 
Description:  If the property permits, multiple "date" values are 
specified as a COMMA-separated list of values.  The format for the 
value type is based on the [ISO.8601.2004] complete 
representation, basic format for a calendar date.  The textual 
format specifies a four-digit year, two-digit month, and two-digit 
day of the month.  There are no separator characters between the 
year, month, and day component text. 
No additional content value encoding (i.e., BACKSLASH character 
encoding, see Section 3.3.11) is defined for this value type. 
Example:  The following represents July 14, 1997: 
19970714

[中]RFC5445中定义的日期对象的表示形式。
注意：默认情况下，iCal4j计算日期对象的时区。在iCalendar规范中，日期对象实际上没有与之关联的时区，但在ical4j实现中，它有与之关联的时区（因为它基于java.util.DATE对象）。这样做的一个不幸的副作用是，日期对象可能会受到关联时区的夏令时规则的影响。因此，目前ical4j提供了两种设置时区的方法：
1.使用UTC时间（无DST规则，但取决于日期的构造方式，它可能会更改显示值
1.使用本地时区（在极少数情况下，DST规则可能会影响显示值）。
默认情况下，使用选项1，但您可以在ical4j中使用以下标志覆盖此选项。属性文件：net.fortuna.ical4j.timezone.date.floating=true
或者，您可以避免使用接受java的构造函数。util。对象，而是提供一个日期字符串值。这应始终显示正确的值，但是当使用本地时区时，任何计算（重现等）仍可能受到DST规则的影响。
