do it in sql, this is pretty database dependent, but the ideal way to me
would be just 

where event_date > <dtml-var TimeArguement fmt=dbdateformat>

and just adjust your dtml to call the method with a date arguement.

you probably need to use your db's string->date functions to convert the
value for comparisions.

i think this would offer the best performance, and least code.
