没有内置函数.但是写一个相对容易.由于 Unix 时间戳是自 1970 年 1 月 1 日以来的秒数

There are no built-in functions. But it's relatively easy to write one. Since a Unix timestamp is the number of seconds since January 1, 1970

CREATE OR REPLACE FUNCTION unix_ts_to_date( p_unix_ts IN NUMBER )
  RETURN DATE
IS
  l_date DATE;
BEGIN
  l_date := date '1970-01-01' + p_unix_ts/60/60/24;
  RETURN l_date;
END;

你可以看到被调用

SQL> select unix_ts_to_date( 1336822620 ) from dual;

UNIX_TS_TO_DATE(133
