UTC时间戳是从1970年1月1日00:00:00开始的毫秒数。我们可以通过将当前毫秒数减去这个起始时间来获得UTC时间戳。 longutcTimestamp=currentTimeMillis-calendar.getTimeZone().getRawOffset(); 1. 类图 下面是本文中使用到的类图: Calendar+getInstance() : Calendar+setTimeZone(timeZone: TimeZone)+getTimeInMill...
public void getCurrentUtc8Time() { // 获取UTC+8时区 ZoneId utc8ZoneId = ZoneId.of("UTC+8"); // 获取当前时间 ZonedDateTime now = ZonedDateTime.now(utc8ZoneId); // 格式化为字符串 DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"); String currentTime = ...
但是,Joda-Time 团队确实建议迁移到 java.time。System.out.println( "UTC/GMT date-time in ISO 8601 format: " + new org.joda.time.DateTime( org.joda.time.DateTimeZone.UTC ) ); 更详细的示例代码(Joda-Time 2.3)……org.joda.time.DateTime now = new org.joda.time.DateTime(); // Default t...
java中把UTC时间戳(System.currentTimeMillis())转化为代表日期的整数 - CSDN博客 currentTimeMillis,getTimeInMillis与getTime获取当前时间戳耗时比较 - CSDN博客 date.gettime()返回的是什么? - - ITeye博客 java.util.Calendar.getTime()方法实例 - Java.util包™ System.currentTimeMillis()/1000_百度搜索 ...
System.out.println("local millis = " + cal.getTimeInMillis());//等效System.currentTimeMillis() , 统一值,不分时区//从本地时间里扣除这些差量,即可以取得UTC时间:cal.add(java.util.Calendar.MILLISECOND, -(zoneOffset +dstOffset));longmills =cal.getTimeInMillis(); ...
