Scala 将时间戳转成指定时区的时间（UTC时间）

package import java.text.SimpleDateFormat import java.util.{Calendar, Date, TimeZone} object Test { def main(args: Array[String]): Unit = { val time2: Double = 1554506596858d; //换成0失去 val sdf: SimpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss Z")//.setTimeZone(TimeZone.getTimeZone("UTC")) sdf.setTimeZone(TimeZone.getTimeZone("UTC")) val result2=sdf.format(time2)//.setTimeZone(TimeZone.getTimeZone("UTC")) // formatTime. // utcFormater.setTimeZone(TimeZone.getTimeZone("UTC"));/ //2019-04-06 07:23:16 System.out.println("13位数的时间戳（毫秒）--->Date:" + result2); import java.util.Calendar } }
