# You do need to talk to an NTP server or two (or three). | |

# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server will | |
# pick a different set every time it starts up. Please consider joining the | |

# up blocking replies from your own upstream servers. | |
# By default, exchange time with everybody, but don't allow configuration. | |
