The OP said NSDateComponents, not NSCalendarDate. NSDateComponents
will not be deprecated any time soon. And despite what the docs say,
I don't think NSCalendarDate is going away soon, because only
NSCalendarDate supports encapsulating a time zone within a date.
In any case, if you can avoid using NSCalendar/NSDateComponents to
make a calendrical calculation, I'd recommend you do so. NSCalendar
is quite slow to make even the most basic of calculations,
especially on PPC Macs.
Certainly in a tight loop it might not be appropriate to use
NSCalendar but the OP was using them for display in a timer that only
fired once a second. I'd argue that the NSCalendar/NSDateComponns
method calls are more readable than modulo arithmetic for most people.
I'd be interested in knowing what kind of performance you saw on PPC
Macs though that would cause you to write them off in all situations.
I've not come across that in my testing.
