|

// 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.
