Bill, that does look like it will work well, In my initial playing it
does not seem to be the most intuitive thing but so many things in IDL
are not that I am getting more and more used to them. Like the extra
"axis" that is drawn by default, but I have seen in help somewhere
examples that did not have that.
Cheers,
Brian

Brian,
Better yet, see the system variable !xtickformat:
"Set this keyword to a string or a vector of strings. The string can
be a format string or a string containing the name of a function that
returns a string to be used to format the axis tick mark labels. If a
vector is provided, each string corresponds to a level of the axis.
" (see idl help on !xtickformat for more information.)
You need to provide a function to format the labels for each level,
then set:
!xtickformat=['label_funct_1', 'label_funct_2, ...]
This should do what you want.
Cheers,
Bill

Well, I would use the information in !Y.CRANGE (data
coordinates) or in !Y.WINDOW (normalized coordinates)
to help me align the extra annotation in the Y direction
(ALIGN=0.5 on your XYOUTS command, after you rotate it).
Positioning in the X direction is usually done more
empirically. (That is to say, you have to try it 2-3 times,
usually.) But if you base if off of !X.CRANGE[0] or
!X.WINDOW[0] you can usually find the right place in a matter
of seconds.
Cheers,
David

Brian,
Check out the 'label_date' function in idl help. That function allows
you to put multiple line date/time labels on plots (see the examples
at the end of the help page.) You may be able to tweak it to do what
you want.
Cheers

You may try adding !C to the ticknames:
plot,[1,2,1],xtickname=['','','1!C1']
Cheers,
