It tells you when to retry the pool DNS so you will get new data.

0.fedora.pool.ntp.org. 150 IN A 74.82.59.150
0.fedora.pool.ntp.org. 150 IN A 104.131.53.252
0.fedora.pool.ntp.org. 150 IN A 45.127.112.2
0.fedora.pool.ntp.org. 150 IN A 208.53.158.34
The 150 is the TTL.
Of course, a caching DNS server might drop them sooner. Then an earlier
reload might get a different answer, but if all goes well, that's a good and
polite time to wait.
