app_time

What time the device thinks it is, in its own zone — what a clock-dependent screen shows, and what a test of scheduling or a timezone change checks against. A phone and an emulator read their own clock; an iOS simulator has none and reads the Mac's, and says so. To change the zone, app_timezone.
Read-only: readOnlyHint is true.
Arguments
| Name | Type | Required | What it is |
|---|---|---|---|
device | string | Device serial to target, e.g. "emulator-5554". Omit when only one device is running. | |
driver | string: uiautomator2, uiautomator, wda | Driver to use: "uiautomator2" (default for Android; fast, installs a server APK on first use), "uiautomator" (Android, installs nothing, slower, cannot type), or "wda" (WebDriverAgent: iOS simulators and iPhones). |
