[iOS] Timer corrupts when app goes in back ground and comes to foreground

[yasir-syed]

In iOS when app goes in back ground and comes to foreground the timer reduces the time more that it should have, e.g. if i stay in background for 5 seconds and comes back to app screen it reduces 10-15 seconds. However, on Android I am not experiencing the same behavior. For Android its working correctly.

"react": "16.9.0",
"react-native": "0.61.5",
"react-native-countdown-component": "^2.7.1",

I'm experiencing the same issue on android
when the internet goes on/off timer is stuck for a while and then again starts working usually.
also, sometimes seconds are ellipses on moving background/foreground.
