Yes, currently the 'samba' side of things (compared with smbd) doesn't
know how to substitute the macros.  Now part of this is due to global
variables and multiple clients per connection, but it doesn't really
excuse us also skipping things like %T.

I think this is because each process only checks if the file should be
rotated every few lines, so they can hold the log open for quite some
time.  Ideally a global signal would be sent saying which file (or even
just that a file) just got rotated, so everyone can re-open.  

Patches are most welcome!
