%description
    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 accuracies typically within a millisecond on LANs and
    up to a few tens of milliseconds on WANs relative to Coordinated
    Universal Time (UTC) via a Global Positioning Service (GPS)
    receiver, for example. Typical NTP configurations utilize multiple
    redundant servers and diverse network paths in order to achieve high
    accuracy and reliability. Some configurations include cryptographic
    authentication to prevent accidental or malicious protocol attacks
    and some provide automatic server discovery using IP multicast.
