将伦敦时间和日期转换为 GMT +6 时间和日期

Question

我从Google收集了伦敦时间。我想获得 GMT+6 时间和日期。我尝试了很多方法，但我无法到达目的地。谁能帮我解决这个问题。我已将所有 string 转换为 int 。

这是我的代码：

   CurrentDate = Date[1]+"/"+Month+"/" + Date[3];
             //  String dateFormat = Date[0]
                String[] Timee = Date[4].split(":");
                int hour = Integer.parseInt(Timee[0]);

                Log.e("Timeee", hour + " -- " + Timee[1] + " --" + Timee[2]);
                int seconds = Integer.parseInt(Timee[2]);
                int minutes = Integer.parseInt(Timee[1]);
                CurrentTime = seconds + minutes + hour;

                int date = Integer.parseInt(Date[1]);
                int year = Integer.parseInt(Date[3]);

                CurrentTime2 = Date[3]+"-" + Month +"-"+"-" + Date[1] +" " + hour+":" +Timee[1]+":"+Timee[2];





                 Date date1 = null;
                SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                try {
                    date1 = sdf.parse(CurrentTime2);
                }catch (Exception e){

                }
                sdf.setTimeZone(TimeZone.getTimeZone("Asia/Kolkata"));
                //        System.out.println(sdf.format(date));
                Log.e("@@@Date: ",String.valueOf(sdf.format(date1)));
                 DateAndTime = String.valueOf(sdf.format(date1));

Convert UTC to current locale time

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
Date myDate = simpleDateFormat.parse("your data string");

如果你想要任何时区而不是遵循这个

您需要使用相同的日期格式解析日期

 SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    String dd = "2018-01-29 12:35:00";




    Date date = null;
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    try {
        date = sdf.parse(dd);
    }catch (Exception e){

    }
    sdf.setTimeZone(TimeZone.getTimeZone("America/Belize"));
 //        System.out.println(sdf.format(date));
    Log.e("@@@Date: ",String.valueOf(sdf.format(date)));

输出

2018-01-29 01:05:00（格林威治标准时间 6）

亚洲时区（印度）

 SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    String dd = "2018-01-29 12:35:00";




    Date date = null;
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    try {
        date = sdf.parse(dd);
    }catch (Exception e){

    }
    sdf.setTimeZone(TimeZone.getTimeZone("Asia/Kolkata"));
  //        System.out.println(sdf.format(date));
    Log.e("@@@Date: ",String.valueOf(sdf.format(date)));

输出

2018-01-29 12:35:00 GMT+05:30

您可以将 GMT 时间增加 6 小时。

获取伦敦时间并将其转换为GMT。
现在根据需要在该时间基础上增加 6 小时 GMT +6 .

Calender calender = Calender.getInstance(); calender.setTime("Enter GMT Time Here); calender.add(Calender.Hour, 6); System.out.println("Date/Time Here " +calender.getTime());

将伦敦时间和日期转换为 GMT +6 时间和日期
