] | Since this string is in ISO format, the casting can be done straightforward
```
hive> select cast("2017-07-31 23:48:25.957" as timestamp);
OK
2017-07-31 23:48:25.957

or
```
hive> select timestamp("2017-07-31 23:48:25.957");
OK
2017-07-31 23:48:25.957
``` | because unix\_timestamp is based on seconds, it truncate milliseconds.
Instead, you can transform string to timestamp using date\_format, which preserve milliseconds. And then from\_utc\_timestamp.
```
select from_utc_timestamp(date_format("2017-07-31 23:48:25.957",'yyyy-MM-dd HH:mm:ss.SSS'),'UTC') as datetime
