Martijn Visser updated FLINK-37753:
-----------------------------------
    Description: 
Right now, running a UNIX_TIMESTAMP like:

{code:sql}
SELECT UNIX_TIMESTAMP('2025-04-30T19:20:17Z');
{code}

Returns a value like 
{noformat}
-9223372036854776000
{noformat}


Instead of returning the minimum of a LONG, we could return an error because 
the format is not according to the provider (in this case, the default) format
