Description:
This query:

SELECT * FROM utc_time;

returns an error:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'dt2' at line 1

This is wrong.
UTC_DATE, UTC_TIME, UTC_DATETIME  are not mentioned in the list of reserved keywords in the SQL Standard, and nothing in the grammar in sql_yacc.yy prevents them from being non-reserved.

How to repeat:
SELECT * FROM utc_time;

Hello Alexander,

Thank you for reporting this!

Note: UTC_DATETIME is a regular identifier in MySQL. I guess the reporter means UTC_TIMESTAMP instead.

Sorry for a mistake in the original report. I mean UCS_TIMESTAMP instead of UTC_DATETIME.

UTC_TIMESTAMP that is :)
