Problem with Interface Clock

[beli]

I am having problems with my interface
clock. When the clock is configured with
the option "Configuration-Set Interface
Clock", seemingly the time is synchronized
with my computer time. But after one day
working, the time becomes out of sync. I
already replaced the batteries by a new
ones, but the problem still remains. What
can I do ?

Beli,
What X10 interface are you using?
