Yes, you can use the Unix timestamp function in Kudu. The function is called "unix_timestamp", and it returns the number of seconds since the Unix epoch (January 1, 1970, UTC) for a given date or timestamp.
Here is an example of how to use the unix_timestamp function in Kudu:
```
SELECT unix_timestamp(date_column) AS unix_time
FROM kudu_table;
```
This will return the Unix timestamp for the "date_column" column in the "kudu_table" table. You can also use the unix_timestamp function with a format string to convert a string to a Unix timestamp. For example:
```
SELECT unix_timestamp('2022-01-01 00:00:00', 'yyyy-MM-dd HH:mm:ss') AS unix_time
FROM kudu_table;
```
This will return the Unix timestamp for the date '2022-01-01 00:00:00'.
