iOS-ntp
This project is a mirror of the iOS-ntp project hosted on Google code by Gavin Eadie
Notes
The structure of this project may need some cleaning up and modernisation but it is ARC compatible and runs fine on Xcode 4.6.2.
It probably neeeds to be worked around a newer version of Cocoa Async Socket https://github.com/mattsoftware/CocoaAsyncSocket
Running the project
git clone git://github.com/jessedc/iOS-ntp.git ios-ntp
cd ios-ntp
git submodule sync
git submodule update --init
open ntpA.xcodeproj
Original README
An application testbed and a network time protocol client for iOS. This is a work in progress.
The clock on an iPhone, iPod Touch and iPad is not closely synchronized to the correct time. In the case of a device with access to the telephone system, there is a setting to enable synchronizing to the phone company time but that time has been known to be over a minute different from UTC.
This project contains code to provide time obtained from standard time servers using the network time protocol (NTP: RFCs 4330 and 5905). The implementation is not a rigorous as described in those RFCs since my goal was to improve time accuracy to within a second, not to fractions of milliseconds.
