有一种方法：

beeline> select date_format(cast(unix_timestamp('04/19/2020 09:30:59 AM','MM/dd/yyyy HH:mm:ss a')*1000 as timestamp),'yyyy-MM-dd\'T\'HH:mm:ss\'Z\'');

+-----------------------+
|          _c0          |
+-----------------------+
| 2020-04-19T09:30:59Z  |
+-----------------------+
1 row selected (0.255 seconds)

但是，如果您自己的时区不是utc，那么您可能应该替换为simple cast(... as timestamp) 通过typecast+时区转换 to_utc_timestamp() :

beeline> select date_format(to_utc_timestamp(unix_timestamp('04/19/2020 09:30:59 AM','MM/dd/yyyy HH:mm:ss a')*1000,'EST'),'yyyy-MM-dd\'T\'HH:mm:ss\'Z\'');

+-----------------------+
|          _c0          |
+-----------------------+
| 2020-04-19T14:30:59Z  |
+-----------------------+
1 row selected (0.236 seconds)
