There are times  you look for something simple, and get very frustrated. One of those for me was getting a freaking time stamp on my app.

After a bit of chasing around, I did find this in Apple’s documentation, in case you are looking for it.

// code to get the date and time  in a string.
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateStyle:NSDateFormatterMediumStyle];
    [dateFormatter setTimeStyle:NSDateFormatterMediumStyle];
    NSDate *date = [NSDate date];
    NSString *formattedDateString = [dateFormatter stringFromDate:date];

Note there are other constant you can use besides NSDateMediumStyle.
