System time changes can stop timers about cocos2d-iphone HOT 6 CLOSED

as a quick workaround add this to calculateDeltaTime (Director.m):

dt = MAX(0,dt); // line 499

BTW, why are you changing the time backwards ?

Im not doing it myself, it seems like the phone adjusts the time by itself 
probably in some automated 
background fashion. it doesn't happen often but I've seen it 2-3 times now that 
the phone jumps seconds 
forwards or backwards.

I was hoping there was a universal uptime counter to use instead, but it seems 
like "UpTime", which some people 
suggests, is not available (or I cant find the right library to add for it). 
But it must be possible since the internal 
NSTimer calls is not affected by time changing it seems.

actually its a known thing that time might change significantly at certain time 
(network time updates and 
similar). the application delegate gets a call 

- (void)applicationSignificantTimeChange:(UIApplication *)application

when it happens, but there are no obvious way to get the adjusted time change, 
but its probably fair to just call 
the director with that info as well and make it handle it better (assuming the 
average time has passed since the 
last timer was called or something similar).

thanks for the info.
