Shrinking TTL or ??

[William Webb]

In the zone below, ns1.ultradns.net is the master.   In the 
additional section of the master it shows:

ns1.ultradns.net.       1D IN A         204.69.234.1

But in the additional section of one of the slaves it shows:

ns1.ultradns.net.       17h34m16s IN A  204.69.234.1

Why the lower value, what does this signify?

Also, what factor determine the order in which the servers are listed 
in the authority or additional section of these dig inquiries?
