Caveats: I remember this coming up but I don't remember exactly when or
in what context. (If you have a URL where you got this I could double
check.) And I don't use the script in question, since I get the same
functionality (faster) through a patch to mutt's code.
It looks to me like there's an error in the documentation:

There should be two arguments to the script, but the $index_format
there passes only one. You also need the current timestamp.
The simplest solution is probably to change the script: replace
this line:
now="$2" # local current time in epoch seconds
with this:
now=$(date +%s)
But I haven't tested this. Maybe Ed will see this and have a better
answer.
