There is no "best" NTP server, that really makes no sense, not least becuase you should never just use one server. just point your machine to 0.pool.ntp.org, 1.pool.ntp.org and 2.pool.ntp.org and you'll be fine. There are also more regional services, which you can get further dns names from www.ntp.org
Don't make it look like windows or mac. it's fine how it is - why just try to blindly copy??
