ShadowSystemClock

public ShadowSystemClock()

Method Details

currentTimeMillis

public static long currentTimeMillis()

Implements System.currentTimeMillis() through ShadowWrangler.

Returns:

Current time in millis.

nanoTime

@Deprecated public static long nanoTime()

Deprecated.

Don't call this method directly; instead, use System.nanoTime().

Implements System.nanoTime().

Returns:

Current time with nanos.

setNanoTime

public static void setNanoTime(long nanoTime)

Sets the value for System.nanoTime().

May only be used for LooperMode.Mode.LEGACY. For LooperMode.Mode.PAUSED, {@param nanoTime} is calculated based on SystemClock.uptimeMillis() and can't be set explicitly.

setNetworkTimeAvailable

public static void setNetworkTimeAvailable(boolean available)

Sets whether network time is available.

advanceBy

public static void advanceBy(long time, TimeUnit unit)

An alternate to advanceBy(Duration) for older Android code bases where Duration is not available.

advanceBy

public static void advanceBy(Duration duration)

A convenience method for advancing the clock via SystemClock.setCurrentTimeMillis(long)

Parameters:

duration - The interval by which to advance.

currentGnssTimeClock

@Implementation(minSdk=29) protected static Object currentGnssTimeClock()

setGnssTimeAvailable

public static void setGnssTimeAvailable(boolean available)

Sets whether gnss location based time is available.

reset

public static void reset()
