Barycentric Julian Date

This is probably a question for Arne. Has AAVSO given any thought to adding Barycentric Julian #DATE choices in the WebObs header? At last summer's CCD school Arne pointed out that HJD provides a much more consistent temporal frame of reference than JD (GJD). BJD is even more consistent than HJD. WET data on white dwarfs, for example, is done in BJD because extremely accurate as well as precise timing of the millihertz pulsation is required. I have also noticed that a number of professional exoplanet observations are made using BJD.
