我使用了以下功能，但是没有用. "UNIX_TIMESTAMP(event_time_stamp)"

UNIX时间戳表示自1970年1月1日以来经过的秒数.Oracle允许直接在时间戳中添加一些天数.我们可以通过将UNIX时间戳值中的适当天数添加到1970-01-01 00:00:00:
The UNIX timestamp represents the number of seconds which have elapsed since January 1, 1970. Oracle allows adding some number of days directly to a timestamp. We can build the timestamp you want by adding the appropriate number of days in your UNIX timestamp value to 1970-01-01 00:00:00:
SELECT
TIMESTAMP '1970-01-01 00:00:00' + NUMTODSINTERVAL(1511421211, 'second')
FROM dual;
这将返回以下内容:
