João Pedro Antunes Ferreira commented on ARROW-12189:
-----------------------------------------------------
I added in the same Pull Request, the implementation for IS_DATE functions:
* *IS_DATE([string] timestring, [string] format)* - Returns true if the string
is castable for the format specified.
* *IS_DATE**([string] timestring)* - Returns true if the string is castable
for the default format ‘YYYY-MM-DD’.

> The function has similar behavior to the existent *TO_DATE([string]
> given_text, [literal_string] format)* function, but it returns the
> information about the hours, minutes, seconds, and milliseconds in the
> response.
