Anthony Louis Gotlib Ferreira commented on ARROW-12189:
-------------------------------------------------------
I added in the same Pull Request, the implementation for UNIX_TIMESTAMP
functions:
* *UNIX_TIMESTAMP([string] timestring, [string] format)* - Gives the Unix time
for the date in timestring using the format specified in format.
* *UNIX_TIMESTAMP([string] timestring)* - Gives the Unix time for the date in
timestring assuming a format of ‘YYYY-MM-DD HH24:MI:SS’.
> [C++][Gandiva] Implement TO_TIME([string] given_text, [literal_string]
> format) and TO_TIMESTAMP([string] given_text, [literal_string] format) and
> UNIX_TIMESTAMP functions

> information about the hours, minutes, seconds, and milliseconds in the
> response.
