You shouldn't need to convert to an NSString. NSCalendarDates are
NSDates, so you should just be able to pass in an NSCalendarDate
wherever an NSDate is requested.
//broken up into multiple ops for clarity
NSCalendarDate* calendarDate = [myDate dateWithCalendarFormat:nil timeZone:nil];
NSCalendarDate* roundedDate = [calendarDate dateByAddingYears: 0
months: 0
days: 0
hours: 0
minutes: - [calendarDate minuteOfHour]
seconds: 0];
[someObject doNeatThingWithDate:roundedDate];
