Gengliang Wang 2bdd9fe5e3 [SPARK-35839][SQL] New SQL function: to_timestamp_ntz ... ### What changes were proposed in this pull request? Implement new SQL function: `to_timestamp_ntz`. The syntax is similar to the built-in function `to_timestamp`: ``` to_timestamp_ntz ( <date_expr> ) to_timestamp_ntz ( <timestamp_expr> ) to_timestamp_ntz ( <string_expr> [ , <format> ] ) ``` The naming is from snowflake: https://docs.snowflake.com/en/sql-reference/functions/to_timestamp.html ### Why are the changes needed? Adds a new SQL function to create a literal/column of timestamp without time zone. It's convenient for both end-users and developers. ### Does this PR introduce _any_ user-facing change? Yes, a new SQL function `to_timestamp_ntz`. ### How was this patch tested? Unit tests Closes #32995 from gengliangwang/toTimestampNtz.
