I'm not sure what we're supposed to do about such sabotage on the
network, that seems distinctly a local issue. We should do the best we
can right now, while providing a manual switch for the user to alter
the default.

It used to be the case that we used these servers:
0.fedora.pool.ntp.org
1.fedora.pool.ntp.org
2.fedora.pool.ntp.org
3.fedora.pool.ntp.org

Chrony isn't installed or running on Fedora 21 Server, so at least on
server I have no idea at the moment were the ntp pool is specified.

Time is a basic requirement, it's correct for Fedora installs to point
to a Fedora Project ntp pool by default for Server and Workstation
products; for cloud they may have different (?) requirements. I expect
"manual time" setting to be exist, and it'd be synonymous with ntp
off.

The pool still exists. Are we not supposed to use them?
