Question

我有一个客户端应用程序在GMT时间发送到我的SQL数据库，我需要在PST中显示此TIME，我如何在JAVA和javascript中执行此操作？我需要获取存储在数据库中的GMT时间，如2016-02-05 14:45:05，并以PST时间格式显示。

一些例子

Convert time between timezone

Converting Times Between Time Zones

import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.TimeZone;

public class TimeZoneExample {
    public static void main(String[] args) {
        // Create a calendar object and set it time based on the local
        // time zone
        Calendar localTime = Calendar.getInstance();
        localTime.set(Calendar.HOUR, 17);
        localTime.set(Calendar.MINUTE, 15);
        localTime.set(Calendar.SECOND, 20);

        int hour = localTime.get(Calendar.HOUR);
        int minute = localTime.get(Calendar.MINUTE);
        int second = localTime.get(Calendar.SECOND);


        // Print the local time
        System.out.printf("Local time  : %02d:%02d:%02d\n", hour, minute, second);


        // Create a calendar object for representing a Germany time zone. Then we
        // wet the time of the calendar with the value of the local time

        Calendar germanyTime = new GregorianCalendar(TimeZone.getTimeZone("Europe/Berlin"));
        germanyTime.setTimeInMillis(localTime.getTimeInMillis());
        hour = germanyTime.get(Calendar.HOUR);
        minute = germanyTime.get(Calendar.MINUTE);
        second = germanyTime.get(Calendar.SECOND);


        // Print the local time in Germany time zone
        System.out.printf("Germany time: %02d:%02d:%02d\n", hour, minute, second);
    }
}

如何将时间从GMT转换为PST？
