                String serial, 
                String cmd, 
                long timeoutMs)

Executes adb command and returns response if succeed.

Parameters
`deviceManager`	`IDeviceManager`: the IDeviceManager instance for executing command on "Available" devices.
`serial`	`String`: the device serial.
`cmd`	`String`: the command string.
`timeoutMs`	`long`: the time to wait in milliseconds.

Returns
	A `CommandResult` instance.

GetCurrentTimestamp

public static Timestamp GetCurrentTimestamp ()

Gets current timestamp from system UTC clock.

Returns
`Timestamp`

RoundedMetricValue

public static float RoundedMetricValue (String original)
