如何从毫秒到GMT获得时间

Question

需要在GMT中显示时间......但它以UTC显示

long m=Long.parseLong("1444588200000");

  Date localTime = new Date(m);

  Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"),
          Locale.getDefault());
DateFormat date = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS");
String time = date.format(localTime);
    infoip.setText(" "+time);

Answer 1

试试这个，

final Date currentTime = new Date(); 

final SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS");

// Give it to me in GMT time. 
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
System.out.println("GMT time: " + sdf.format(currentTime));

Answer 2

尝试这样的希望工作。

Calendar cal = Calendar.getInstance();

// setting the timezone for which you want
cal.setTimeZone(TimeZone.getTimeZone("GMT"));
cal.setTimeInMillis();

// The date is in your home timezone 
Date date = cal.getTime();
TimeZone tz = TimeZone.getTimeZone("GMT");
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS", Locale.GMT);
sdf.setTimeZone(tz);
// Then we do the conversion to convert the date you provided in milliseconds to the GMT timezone
String result = sdf.parse(date);
