"$pkgname (Network Time Protocol daemon)"
"The Network Time Protocol (NTP) is used to synchronize the time of a"
"computer client or server to another server or reference time source,"
"such as a radio or satellite receiver or modem. It provides client"
"accuracies typically within a millisecond on LANs and up to a few tens"
"of milliseconds on WANs relative to a primary server synchronized to"
"Coordinated Universal Time (UTC) via a Global Positioning Service"
"(GPS) receiver, for example."

# External servers: The hostnames '*.pool.ntp.org' point to different
# servers each time, using a round robin system. If your ISP has an ntp
# server you want to replace these ones with it. It is not good
# practice to pick a 'stratum 1' server for the synchronisation of a
# single client, so don't put one here please. Read more about picking
# the right ntp servers to use at: http://www.pool.ntp.org/use.html
