title: NSDatePicker timezone weirdness
body: <p>I have an NSDatePicker in my nib file.  In code, I set it's timezone to be the GMT calendar's timezone:</p>
  
  <pre><code>[datePicker setTimeZone:[calendar timeZone]];
  </code></pre>
  
  <p>I only really care about the time (hours, minutes) on the datepicker which I populate programmatically:</p>
  
  <pre><code>NSDate *anyDate = [NSDate date];
          NSDateComponents *components = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit) fromDate:anyDate];
          [components setHour:hours];
          [components setMinute:minutes];
          NSDate *newDate = [calendar dateFromComponents:components];
          [datePicker setDateValue:newDate];
  </code></pre>
  
  <p>This correctly has the desired effect of setting the date pickers time to the time I want.  So if hours is 8 and minutes is 30, the date picker shows 8:30.  However, if I type an 8 into the hour field of the date picker it displays as a 3.  Something weird is going on with timezones somewhere but I'm not sure where...</p>
