1.8.2 srfi-19 warns about current-time

[Gregory Marton]

In guile-1.8.2 (use-modules (srfi srfi-19)) warns:
   WARNING: (guile-user): imported module (srfi srfi-19) overrides core
   binding `current-time'

Apparently one can control this using the #:replace keyword:
http://www.gnu.org/software/guile/manual/html_node/Creating-Guile-Modules.html#Creating-Guile-Modules

Is there some reason srfi-19 doesn't use this?

Thanks,
Grem
