Z表示“零时偏移”,在ISO 8601时间表示中也称为“祖鲁时间”(UTC)。但是,ACP 121标准定义了军事时区列表,并从格林威治标准时间(GMT)得出“祖鲁时间”。
让我们看看SimpleDateFormat(“ HH:mm:ss Z”)的用法-
Format f = new SimpleDateFormat("HH.mm.ss Z"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult);
以下是显示偏移时间(HH:mm:ss Z)的完整示例-
import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { //显示当前日期和时间 Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s"); System.out.println("Today's date = "+simpleformat.format(cal.getTime())); //当前时间 Format f = new SimpleDateFormat("HH.mm.ss Z"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult); //显示小时 f = new SimpleDateFormat("H"); String strHour = f.format(new Date()); System.out.println("Current Hour = "+strHour); //显示分钟 f = new SimpleDateFormat("mm"); String strMinute = f.format(new Date()); System.out.println("Current Minutes = "+strMinute); //显示秒 f = new SimpleDateFormat("ss"); String strSeconds = f.format(new Date()); System.out.println("Current Seconds = "+strSeconds); } }
输出结果
Today's date = 26/November/2018 08:52:33 Time = 08.52.33 +0000 Current Hour = 8 Current Minutes = 52 Current Seconds = 33
