请告诉我如何将毫秒转换为joda日期时间??
object PicklingIteratorExample extends App {
import scala.pickling.Defaults._
import scala.pickling.binary._
import scala.pickling.static._
case class Person(name: String, age: Int)
val personsIt = Iterator.from(0).take(10).map(i => Person(i.toString, i))
val pklsIt = personsIt.map(_.pickle)
??? // Write to disk
val readIt: Iterator[Person] = ??? // Read from disk and unpickle
}
甚至尝试过
formatter = DateTimeFormat.forPattern("dd/MM/yyyy'T'HH:mm:ss").withZone(DateTimeZone.forOffsetHoursMinutes(00, 00));

@Adam S给出的答案几乎没问题。但是,我更愿意明确指定时区。如果不指定它,您将在系统时区中获得构造的DateTime
- 实例。但是你想要区域" 0000" (世界标准时间)?然后寻找替代constructor:
String milliseconds = "14235453511";
DateTime someDate = new DateTime(Long.valueOf(milliseconds), DateTimeZone.UTC);
System.out.println(someDate); // 1970-06-14T18:17:33.511Z
答案 1 :(得分:14)
有a constructor that takes milliseconds:
long milliseconds = 14235453511;
DateTime someDate = new DateTime(milliseconds);
答案 2 :(得分:-2)
您可以使用此
Calendar calendar = new GregorianCalendar();
DateFormat formatter = new SimpleDateFormat("dd MMM yyyy HH:mm:ss z");
formatter.setCalendar(calendar);
String timeZone = "GMT+2:00";
formatter.setTimeZone(TimeZone.getTimeZone(timeZone));
String time = formatter.format(calendar.getTime());
System.out.println(time);
我希望这会对你有所帮助
