options for 'date' via busybox

[Robin Paulson]

hi all,
i'm trying to use date to print the date in a format i want, but i'm
finding the options difficult to work with. using a full 'date' on my
desktop, i can do:

$ date -d now +%B

to print the name of the month as a text string, but the cut down
version on shr doesn't like this, complaining about the 'now' option
as unknown

does anyone have any ideas how i could do this? the documentation at
busybox.org is brief, but it appears i can't go into this sort of
detail

are there any other apps/scripts/methods around that will return
similar, and run on the freerunner?

cheers
