Events off one hour because adjust for daylight savings not checked

[Leslie]

Hi -

I have a customer who has hundreds of recurring annual
events. Every event after April 5th, 2004 (daylight
savings time) is off by an hour. He did not have the box
checked to adjust for daylight savings. Now he has that
checked, but the events do not seem to automatically re-
adjust. If he goes into the event and clicks the
recurrence button, they adjust. Does he really have to
edit them all manually?

Thanks for any insight!
