I did not really find a doc about this, so I played around with the
parameters too. So I figured out the following (if someone knows better
please correct me):
If you use
	--x WEEK:1:MONTH:1:MONTH:1:0:%X
the printed string comes from the %X , so a few parameters for this  are:
%a	Day of the week (i.e. Mon)
%A      Day of the week (i.e. Monday)
%b      Name of the month (i.e. Mar)
%B      Name of the month (i.e. March) - maybe that's the one you wanted
%c      Date like: Mon Mar 1 00:00:00 2004
%d      Day of the month (like 01)
%D      Date like: 03/01/04
%s      for the Unix date

... (to be continued?)
