Well, while it is certainly nice to be resiliant to such things, I am not convinced though that for a normal client this is really a necessity. The commonly used NTP servers are good enough for most cases and are used in SNTP mode by a multitude of devices and operating systems
Which major operating systems do use by default a SNTP client with pool.ntp.org? Microsoft and Apple use SNTP, but they have their own trusted NTP servers. In the Linux world, I think the most popular choice is the reference NTP implementation and on smaller devices it's the busybox NTP client.
It seems I was wrong here. Mac OS X apparently uses the reference NTP implementation modified to work in combination with another daemon called pacemaker, which adjusts the clock [1] and the w32time service used in Windows does implement the NTP algorithms [2].
It looks like pretty much everyone has a full NTP client running on their system, I'm sure we don't want Fedora to be the exception.
