Handling time units (ms, us) in sort --human-numeric-sort

[Carl Ponder]

(This is a feature request, not a bug report, but I couldn't figure out 
from your website info where else to send it).
I want to use "sort" to order information in the following format

   15us
   9ms
   10s

I know that the--human-numeric-sort is able to manage file size units 
(K, G), but it looks like it is not aware of time units (s, ms, us).
Is this something you can add?
I'm using the sort version 8.13 (on Ubuntu 12.04), do you already have 
this in a more current version?
I don't see it in your list of rejected requests (!) so I figure there's 
a chance....
Thanks,
