long timestamp to LocalDateTime
提问by rhandom
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
我有一个很长的时间戳 1499070300（相当于 2017 年 7 月 3 日星期一 16:25:00 +0800）但是当我将其转换为 LocalDateTime 时，我得到 1970-01-18T16:24:30.300
Here's my code
这是我的代码
long test_timestamp = 1499070300;
LocalDateTime triggerTime =
LocalDateTime.ofInstant(Instant.ofEpochMilli(test_timestamp), TimeZone
.getDefault().toZoneId());

You need to pass timestamp in milliseconds:
您需要以毫秒为单位传递时间戳：
long test_timestamp = 1499070300000L;
LocalDateTime triggerTime =
LocalDateTime.ofInstant(Instant.ofEpochMilli(test_timestamp),
TimeZone.getDefault().toZoneId());
System.out.println(triggerTime);
Result:
结果：
2017-07-03T10:25
Or use ofEpochSecondinstead:
或者ofEpochSecond改用：
long test_timestamp = 1499070300L;
LocalDateTime triggerTime =
LocalDateTime.ofInstant(Instant.ofEpochSecond(test_timestamp),
TimeZone.getDefault().toZoneId());
System.out.println(triggerTime);
Result:
结果：
2017-07-03T10:25

Try with Instant.ofEpochMilli()or Instant.ofEpochSecond()method with it-
尝试Instant.ofEpochMilli()或Instant.ofEpochSecond()使用它的方法-
long test_timestamp = 1499070300L;
LocalDateTime date =
LocalDateTime.ofInstant(Instant.ofEpochMilli(test_timestamp ), TimeZone
.getDefault().toZoneId());

Try with the following..
尝试以下..
long test_timestamp = 1499070300000L;
LocalDateTime triggerTime =
LocalDateTime.ofInstant(Instant.ofEpochMilli(test_timestamp), TimeZone
.getDefault().toZoneId());
By default 1499070300000is int if it dosen't contain l in end.Also pass time in milliseconds.
1499070300000如果最后不包含 l，则默认为 int。也以毫秒为单位传递时间。

Your issue is that the timestamp is not in milliseconds but expressed in seconds from the Epoch date. Either multiply by 1000 your timestamp or use the Instant.ofEpochSecond().
您的问题是时间戳不是以毫秒为单位，而是以从纪元日期开始的秒数表示。将时间戳乘以 1000 或使用Instant.ofEpochSecond().

If you are using the Android threeten back port then the line you want is this
如果您使用的是 Android Threeten back port 那么您想要的线路是这样的
LocalDateTime.ofInstant(Instant.ofEpochMilli(startTime), ZoneId.systemDefault())
