Yes, you are exactly right. Thanks!

Unfortunately, in playing with this I think I discoverd a small bug
(or at least ksh incompatability) in zsh:

------------------------------------------------------------------------------
charney$ ksh
$ TZ=GMT-$((18+$((${2:-1}-1))*24)) date +%j
273
$ ^D
charney$ echo $ZSH_VERSION
2.6-beta10-hzoli10.2
charney$ TZ=GMT-$((18+$((${2:-1}-1))*24)) date +%j
zsh: ')' expected

------------------------------------------------------------------------------
If not a bug, is there an alternate syntax I can use in zsh?

What's wrong with $((18+(${2:-1}-1)*24)) ?  And the line above works
for me (2.6-beta11-test7).

Z> What's wrong with $((18+(${2:-1}-1)*24)) ?

Err, nothing, it should work too but it doesn't:

$ TZ=GMT-$((18+(${2:-1}-1)*24)) date +%j
zsh: ')' expected

Yes, you're right. It works in 2.6-b10 as well, so I presume the bug
is restricted to the hzoli releases (though I've only verified up to
hzoli10.2). I should have checked this prior to my original post to
the list.

Thanks for the info.
