Date and time are the same thing in Cocoa. After all, a span of
time (or point in time) is just a more precise date, right?
You should probably have two columns, both bound to the same
"date" property. Just use a date formatter (see NSDateFormatter) to
make one column display only the "date" string and the other display
only the "time" string.
If you sort by either column, the sorting should be the same, I
would imagine. Perhaps I don't understand what you mean by 'group by'.

Hi, I have a couple of newbie questions about
coredata.
I have a problem with one of my tables. I want to save
the date and time of a message, in SQL I would do a
DATE column and a TIME column so I can group by date
and order by time. How can this be acomplish in
Coredata? Should I use two NSDate columns? How can I
group the messages by date as there is no GROUP BY
statement in Coredata? Do I have to loop manually and
compare dates and time from the result array of the
NSFetchRequest?
thanks
Daniel
