In theory, the UTC offsets countries use should reflect the local mean solar time. However, many time zone boundaries are distorted by geographical and political factors. No Daylight Saving Time in UTC Daylight Saving Time(DST) is not used for UTC as it is a time standard for all time zo...
publicstaticvoidmain(String[] argv){LocalDateTimebjTime=LocalDateTime.now(); Map<String, ZoneOffset> allZoneIdOffSetMap = allZoneIdOffSet2MapByBjTime(bjTime); System.out.println("北京时间"+ bjTime +",美国纽约的偏移量:"+ allZoneIdOffSetMap.get("America/New_York"));// 让当前北京时间深处纽约20...
1. Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times 2. Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply 里面提到说,ZoneId主要是用来做LocalDateTime...

在JDK8之前,Java对时区和偏移量都是使用java.util.TimeZone来表示的。 一般情况下,使用静态方法TimeZone#getDefault()即可获得当前JVM所运行的时区,比如你在中国运行程序,这个方法返回的就是中国时区(也叫北京时区、北京时间)。 有的时候你需要做带时区的时间转换,譬如:接口返回值中既要有展示北京时间,也要展示纽约...
Map<String, ZoneOffset> allZoneIdOffSetMap = allZoneIdOffSet2MapByBjTime(bjTime); System.out.println("北京时间" + bjTime + ",美国纽约的偏移量:" + allZoneIdOffSetMap.get("America/New_York")); // 让当前北京时间深处纽约2021年夏令时时间区间内 ...
Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10). The following tables identify the standard time zone boundaries and the offsets. ...
Map<String, ZoneOffset> allZoneIdOffSetMap = allZoneIdOffSet2MapByBjTime(bjTime); System.out.println("北京时间" + bjTime + ",美国纽约的偏移量:" + allZoneIdOffSetMap.get("America/New_York")); // 让当前北京时间深处纽约2021年夏令时时间区间内 ...

方式一:用Java程序把所有可用的zoneId打印出来,然后查阅 @Test public void test3() { String[] availableIDs = TimeZone.getAvailableIDs(); System.out.println("可用zoneId总数:" + availableIDs.length); for (String zoneId : availableIDs) { ...
