// TODO: reactivate the disabled expectations once emulators are fixed in SauceLabs
// In some old versions of Chrome in Android emulators, time formatting returns dates in the
// timezone of the VM host,
// instead of the device timezone. Same symptoms as
// https://bugs.chromium.org/p/chromium/issues/detail?id=406382
// This happens locally and in SauceLabs, so some checks are disabled to avoid failures.
// Tracking issue: https://github.com/angular/angular/issues/11187
