I am writing an application that requires accurate timing. After asking this question, I have decided to investigate using NTP or maybe Simple NTP.
Is there any open
You can use that open source: https://github.com/huynguyencong/NHNetworkTime
[[NHNetworkClock sharedNetworkClock] syncWithComplete:^{ NSLog(@"%s - Time synced %@", __PRETTY_FUNCTION__, [NSDate networkDate]); }];
And use:
NSDate *networkDate = [NSDate networkDate];
