我有一个UTC时间戳,我想将它转换为本地时间而不使用像API这样的API调用TimeZone.getTimeZone("PST").你到底应该怎么做?我一直在使用以下代码但没有取得多大成功:
private static final SimpleDateFormat mSegmentStartTimeFormatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS");
Calendar calendar = Calendar.getInstance();
try {
calendar.setTime(mSegmentStartTimeFormatter.parse(startTime));
}
catch (ParseException e) {
e.printStackTrace();
}
return calendar.getTimeInMillis();
