description         A versatile implementation of the Network Time Protocol (NTP)
license             GPL-2
platforms           darwin
long_description    Chrony can synchronise the system clock with NTP servers, \
                    reference clocks (e.g. GPS receiver), and manual input \
                    using wristwatch and keyboard. It can also operate as an \
                    NTPv4 (RFC 5905) server and peer to provide a time service \
                    to other computers in the network. \
                    It is designed to perform well in a wide range of \
                    conditions, including intermittent network connections, \
                    heavily congested networks, changing temperatures \
                    (ordinary computer clocks are sensitive to temperature), \
                    and systems that do not run continuosly, or run on a \
                    virtual machine.
