Basically, you have configured it to look at the local host for the time as
well as the other servers. It is successfully getting and setting the time
from the local clock.
I would recommend that you remove all of the 127 entries. I would also remove
the drift file entry until you are confident that you are getting the right
time from the right place. Basically, your ntp.conf should have only:
server sushi.compsci.lyon.edu
server rolex.usg.edu
Alternatively, you could use Red Hat's graphical config tool. I think it is
dateconfig. Just check the box to enable NTP and select the ntp servers from
the list.
