NSDate hour description is wrong.  It is appending the 24 hour description and 12 hour description together.

In iOS 10 Settings:
- Set Region to Japan in Settings > General > Language & Region > Region Formats > Region
- Set 24-Hour Time Off in Settings > General > Date & Time > 24-Hour Time

Connect a device to Xcode and check log

NSLog(@"Date is %@", [NSDate date].description);

Expected Result:
Date is 2016-11-13 10:28:27 AM +0000

Acutal Result:
Date is 2016-11-13 1010:28:27 AM +0000

This bug is still occurring in iOS 11 and even iOS 12
