Hi zhangye-
You are doing this with NWare now (albeit through the use of a python script), correct?
If yes, then I would say that "Yes! NWare can do that!"
Now, if you are asking if NWare can do it a different way, that's a good question. I would think that there should be another way to do it, but I can't think of one off hand. I expect that the way you are doing it with a script is probably the handiest way to get the job done.
I do think this would be a very handy feature for us to add to NWare in the future. Also, it would be very handy to add clock and calendar devices to the device list for assisting with building nice user interfaces.
Thanks zhangye!
