Aninc(tm) technology is Unsatisfactory Software's amazing new invention for
FACTS 2.7. It basically allows FACTS to check an alternative local server
if a request to the specified one fails - without you even needing to know
the address!

How it works

Aninc(tm) is possible due to the following:

* A lot of sites have more than one NTP server, to allow NTP clients to peer
with several servers on the same network.

* Due to the fact the servers are on the same network, they all have the
same domain name and are all guaranteed to be local to each other (ie.
one server should respond as quickly as another)

* The actual machine names are (obviously) unique. They tend to be numbered
or lettered in order.

All Aninc does is use the specified server name to generate one which may
exist on the same network.

For example, if you specify the server:
ntp2a.mcc.ac.uk

FACTS will try this first, but if it happens to timeout or otherwise fail,
Aninc (if enabled) will kick in and try the server:
ntp2b.mcc.ac.uk

If this works, great. If it also fails, then you haven't lost anything.
In fact, unless you happen to be watching the FACTS GUI then you won't even
know if Aninc is enabled!

The downside of using Aninc is that FACTS will send a second request if the
first one fails. This may slow things down slightly.

Please note that if your usual server is named clock.*, ntp.*, tick.* or
some other generic name then there will probably be no point in activating
Aninc.

To enable Aninc, select the Settings->On Error->Use Aninc menu item.
