the best way to insert default datetime

[odelya glick]

hi

i have to insert value into a table where it will always be the current time.

my column is of time datetime.

i thought to create a trigger like this:

CREATE TRIGGER insert_date BEFORE INSERT ON usercase FOR EACH ROW SET NEW.caseend = NOW();

what is better for performance: a trigger, or inserting the current date via the code?

thanks
