Disable Graylog Alert on specific time

I believe your pipeline is incorrect.
rule “Between 6 PM and 6 AM”

when
	( to_long(to_date($message.timestamp, "American/Chicago").hourOfDay) >= 0 AND to_long(to_date($message.timestamp, "American/Chicago").hourOfDay) <= 6 ) OR
	( to_long(to_date($message.timestamp, "American/Chicago").hourOfDay) >= 18 AND to_long(to_date($message.timestamp, "American/Chicago").hourOfDay) <= 0 )
then
	set_field("trigger_workhours_off", true);
end

Greater then 6 and less then 6:30, see if that works.

Remember it military time. 
( to_long(to_date($message.timestamp, "American/Chicago").hourOfDay) >= 6 AND to_long(to_date($message.timestamp, "American/Chicago").hourOfDay) <= 6:30 )
