-------------
	+ timeconv -> mjdconv

Version 2.2 - 2001-12-20 (GV)
-----------
	+ DEPEND updated (daltools).
	
Version 2.1 - 2001-10-08 (GV)
-----------
	+ DEPEND: add daltools, needed for test harnesses.
	
Version 2.0 - 2001-10-02 (GV)
-----------
	+ (tabcalc) allows one to set unit and label for the result column
