long timestamp to LocalDateTime

Question

I have a long timestamp 1499070300 (equivalent to Mon, 03 Jul 2017 16:25:00 +0800) but when I convert it to LocalDateTime I get 1970-01-18T16:24:30.300

Here's my code

long test_timestamp = 1499070300;

LocalDateTime triggerTime =
                LocalDateTime.ofInstant(Instant.ofEpochMilli(test_timestamp), TimeZone
                        .getDefault().toZoneId());

If you are using the Android threeten back port then the line you want is this

LocalDateTime.ofInstant(Instant.ofEpochMilli(startTime), ZoneId.systemDefault())

SIMPLE and straight forward solution will (KOTLIN)

            val timeStamp:Long=559585985988
            val sdf = SimpleDateFormat("hh:mm:ss a - MMM dd,yyyy", Locale.getDefault())
            val tz = TimeZone.getDefault()
            val now = Date()
            val offsetFromUtc = tz.getOffset(now.time)
            val localeTimeStr = sdf.format(timeStamp + offsetFromUtc) //add the offset to get the local time from the epoch timestamp
