The constructor is doing that:

<pre><code>Timestamp(long time)

See: <a href="http://docs.oracle.com/javase/7/docs/api/java/sql/Timestamp.html#Timestamp%28long%29"><code>Timestamp.Timestamp(long)</code></a>:

<pre><code>new Timestamp(someLong)

blocks|key|2285182|text|是的，有一个时间戳的构造函数，它需要一个很长的参数。http://docs.oracle.com/javase/6/docs/api/java/sql/Timestamp.html#Timestamp(long)|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2285183|entityMap|0|LINK|mutability|MUTABLE|url|http://docs.oracle.com/javase/6/docs/api/java/sql/Timestamp.html#Timestamp%2528long%2529^0|Q|28|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Yes, there's a constructor for Timestamp that takes a long as a parameter.

blocks|key|646706|text|这个问题有点老了，但对于那些因为时间戳对象不包含(long)构造函数而感到困惑的人来说，Firebase的com.google.firebase.Timestamp对象包含了(Date+date)构造函数。(long+seconds,+int+nanoseconds)和Date确实包含了一个(long)构造函数(它根据纪元开始的秒数创建一个date对象-与java.sql.Timestamp相同|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|646707|底线是你的解决方案是简单的|646708|Timestamp(new+Date(longEpochTimeVar));|code-block|syntax|javascript|646709|或|646710|Timestamp(longEpochTimeVar,0);|646711|0代表0纳秒，因此两个选项都将产生相同的结果。|646712|entityMap|0|LINK|mutability|MUTABLE|url|https://firebase.google.com/docs/reference/android/com/google/firebase/Timestamp|1|https://developer.android.com/reference/kotlin/java/util/Date.html|2|https://developer.android.com/reference/kotlin/java/sql/Timestamp.html^0|O|6|2F|B|2V|V|42|6|1H|T|0|3R|4|1|4Z|I|2|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|14|8|@$9|15|A|16|B|C]|$9|17|A|18|B|C]|$9|19|A|1A|B|C]|$9|1B|A|1C|B|C]]|D|@$9|1D|A|1E|1|1F]|$9|1G|A|1H|1|1I]|$9|1J|A|1K|1|1L]]|E|$]]|$1|F|3|G|5|6|7|1M|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|1N|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|1O|8|@]|D|@]|E|$]]|$1|O|3|P|5|J|7|1P|8|@]|D|@]|E|$K|L]]|$1|Q|3|R|5|6|7|1Q|8|@]|D|@]|E|$]]|$1|S|3|-4|5|6|7|1R|8|@]|D|@]|E|$]]]|T|$U|$5|V|W|X|E|$Y|Z]]|10|$5|V|W|X|E|$Y|11]]|12|$5|V|W|X|E|$Y|13]]]]

This question is a bit old but for those arriving here scratching their heads because their Timestamp object does not include a <code>(long)</code> constructor,
Firebase's <a href="https://firebase.google.com/docs/reference/android/com/google/firebase/Timestamp" rel="nofollow noreferrer">com.google.firebase.Timestamp</a> object include <code>(Date date)</code> constructor. and <code>(long seconds, int nanoseconds)</code>
and <a href="https://developer.android.com/reference/kotlin/java/util/Date.html" rel="nofollow noreferrer">Date</a> does include a <code>(long)</code> constructor (which creates a date object based of number of seconds from epoch - same as <a href="https://developer.android.com/reference/kotlin/java/sql/Timestamp.html" rel="nofollow noreferrer">java.sql.Timestamp</a>

bottom line is your solution is simply either

<pre><code>Timestamp(new Date(longEpochTimeVar));
</code></pre>

or

<pre><code>Timestamp(longEpochTimeVar,0);
</code></pre>

0 stands for 0 nanoseconds so both option will produce the same result.

I know, how to convert a <code>Timestamp</code> to a long, with the <a href="http://docs.oracle.com/javase/8/docs/api/java/sql/Timestamp.html#getTime--" rel="noreferrer"><code>getTime()</code></a> method.

Is there a method that convert a <code>long</code> to a <code>TimeStamp</code>?
