In React Native 0.68 the
Performance.now()
implementation on both iOS and Android changed to use unix epoch timestamps instead of a monotonic clock in facebook/react-native#32695.This is clearly inferior for the purposes of performance metrics as it risks skewing durations, but it's more important to keep the native marks in sync with the RN implementation which this PR aims to do. This means this is a breaking change only compatible with RN >=0.68.
