What I want to do is around every 5 minutes, update the timeInterval

to do this update for a large number of instances of the object. One
way I could think to do this would be to enumerate through the array
containing the objects every 5 minutes and just set the timeInterval
property. But is there a more efficient way to do this?
That sounds plenty efficient, unless you have tens of millions of
these objects. Assuming you only fetch the current date once (which is
somewhat expensive), the operation for each object is basically just
subtracting and storing the result in an instance variable. You're
talking about something on the order of a microsecond or less.
