Timer in waiting game like clash of clans in iOS, clock change user proof

Question

I've read this tutorial and this question, but when i use NSDate() or CFAbsoluteTimeGetCurrent() it is easy to trigger by the user setting the clock forward.

If i use CACurrentMediaTime(), the countdown seems not accurate at long time (1 hour or more).

How can I check the passed time correctly? I must check the time in a server? How?

Thanks

The only really bulletproof way of doing this is via server. However if you can't do this - [this answer may be helpful](http://stackoverflow.com/a/36204651/2976878). — Hamish, Mar 24 '16 at 16:49

You can use a free service such as http://timezonedb.com/api to get the current time. You just need to register for a free API key. No need to add all the extra time of implementing your own server for a simple task like getting the time
