[iOS, il2cpp] System.DateTime.Now is slow on the first run
To reproduce:
1. Open project attached by QA
2. Build it for iOS
3. In XCode's top menu bar select Product -> Profile
4. From the instruments select time profiler
5. After opening Time Profiler hit record button
6. Record for ~10seconds.
7. In the timeline find a spike in CPU usage and make selection on this spike
Expected: System.DateTime.Now should take the same amount of time on all the runs
Actual: On the first run it takes more time (is slower)

Hello. I need help, or at least advice to begin with, about software quality assurance. Who can be contacted with this question?

more info about why this is slow https://stackoverflow.com/a/4075602/1235063
you can use Time.time or a TickCount alternative which doesn't need to query the system time
