Dear All,
  I think we should adopt a standard data/time format in our web
services. First of all, let me remind that the xsd datatype we currently
use for date is xsd:DateTime. 
I suggest we all used the format "E MMM dd HH:mm:ss Z yyyy", for
example: Fri Sep 10 19:49:36 EEST 2010. This will facilitate the parsing
of dates where necessary.

Best Regards,
Pantelis
