Constructor & Destructor Documentation

RealTimeStamp()

UI::Util::RealTimeStamp::RealTimeStamp	(	long int const &	sec = 0,
		long int const &	usec = 0 )

Standard constructor.

Parameters

sec	Seconds since Epoch.
usec	Micro (10^-6) seconds since Epoch+sec.

Note

Values will be "normalised" (make microseconds < 10^6). Altogether, it must not be a negative date (before Epoch).
