public final class
ExactTime¶ Utility class to access the underlying system clock with improved precision compared to the standard Java library capabilities. Various native methods are probed for accessing the time source. If none of them works, this class falls back to
System.currentTimeMillis(), resulting in a reduced precision of the returned time.- Author
