Please describe the problem:
"clock.tl.fukuoka-u.ac.jp" is listed in the NTP server list, but this server is
too much trafficed and it is suggested to use "ntp.jst.mfeed.ad.jp" for personal
use in Japan.
So I think it's good to change "clock.tl.fukuoka-u.ac.jp" to
"ntp.jst.mfeed.ad.jp" in the NTP server list.

Steps to reproduce:
1. Open up time-admin
2. Select a set of nameservers to synchronise with


Actual results:
The list includes "clock.tl.fukuoka-u.ac.jp (Fukuoka, Japan)".

Expected results:
The list should include "ntp.jst.mfeed.ad.jp (Japan)".

Does this happen every time?
Yes
