Yes. Read the UDF header for a desciption of what each parameter is used for, for example:
 Code:
;              DATETIME
;              optional date/time string denoting the start date of the events in
;              the form of YYYY/MM/DD HH:MM:SS, YYY/MM/DD, or HH:MM:SS


If you pass this parameter you should only retrieve events since the date that you specify.

You can also restrict the list by user, computer, event ID or even by passing your own WQL statement if you really want to get into it.
