/* Leap Indicator (LI): 2-bit code warning of impending leap-second to be
|
||||
* inserted at the end of the last day of the current month. Bits are coded
|
||||
* as follows:
|
||||
*
|
||||
* 00 no warning
|

* 01 last minute has 61 seconds
|
||||
* 10 last minute has 59 seconds
|
||||
* 11 alarm condition (clock not synchronized)
|
||||
*
|
||||
* Version Number (VN): This is a three-bit integer indicating the NTP
|
||||
* version number. In this case, three (3).
|
||||
*
|
||||
* Mode: This is a three-bit integer indicating the mode, with values
|
||||
* defined as follows:
|
||||
*
|
||||
* 0 reserved
|
||||
* 1 symmetric active
|
||||
* 2 symmetric passive
|
||||
* 3 client
|
||||
* 4 server
|
||||
* 5 broadcast
|
||||
* 6 reserved for NTP control message (see Appendix B)
|
||||
* 7 reserved for private use
|
||||
*
|
||||
* Stratum: This is a eight-bit integer indicating the stratum level of the
|
||||
* local clock, with values defined as follows:
|
||||
*
|
||||
* 0 unspecified
|
||||
* 1 primary reference (e.g., radio clock)
|
||||
* 2-255 secondary reference (via NTP)
|
||||
*
|
||||
* Poll Interval: This is an eight-bit signed integer indicating the maximum
|
||||
* interval between successive messages, in seconds to the nearest power of
|
||||
* two.
|
||||
*
|
||||
* Precision: This is an eight-bit signed integer indicating the precision
|
||||
* of the local clock, in seconds to the nearest power of two.
|
||||
*
|
||||
* Root Delay: This is a 32-bit signed fixed-point number indicating the
|
||||
* total roundtrip delay to the primary reference source, in seconds with
|
||||
* fraction point between bits 15 and 16. Note that this variable can take
|
||||
* on both positive and negative values, depending on clock precision and
|
||||
* skew.
|
||||
*
|
||||
* Root Dispersion: This is a 32-bit signed fixed-point number indicating
|
||||
* the maximum error relative to the primary reference source, in seconds
|
||||
* with fraction point between bits 15 and 16. Only positive values greater
|
||||
* than zero are possible.
|
||||
*
|
||||
* Reference Clock Identifier: This is a 32-bit code identifying the
|
||||
* particular reference clock. In the case of stratum 0 (unspecified) or
|
||||
* stratum 1 (primary reference), this is a four-octet, left-justified,
|
||||
* zero-padded ASCII string.
|
||||
*
|
||||
* While not enumerated as part of the NTP specification, the following are
|
||||
* suggested ASCII identifiers:
|
||||
*
|
||||
* Stratum Code Meaning
|
||||
* 0 DCN DCN routing protocol
|
||||
* 0 NIST NIST public modem
|
||||
* 0 TSP TSP time protocol
|
||||
* 0 DTS Digital Time Service
|
||||
* 1 ATOM Atomic clock (calibrated)
|
||||
* 1 VLF VLF radio (OMEGA, etc.)
|
||||
* 1 callsign Generic radio
|
||||
* 1 LORC LORAN-C radionavigation
|
||||
* 1 GOES GOES UHF environment satellite
|
||||
* 1 GPS GPS UHF satellite positioning
|
||||
*
|
||||
* In the case of stratum 2 and greater (secondary reference) this is the
|
||||
* four-octet Internet address of the primary reference host.
|
||||
*
|
||||
* Reference Timestamp: This is the local time at which the local clock was
|
||||
* last set or corrected, in 64-bit timestamp format.
|
||||
*
|
||||
* Originate Timestamp: This is the local time at which the request departed
|
||||
* the client host for the service host, in 64-bit timestamp format.
|
||||
*
|
||||
* Receive Timestamp: This is the local time at which the request arrived at
|
||||
* the service host, in 64-bit timestamp format.
|
||||
*
|
||||
* Transmit Timestamp: This is the local time at which the reply departed
|
||||
* the service host for the client host, in 64-bit timestamp format.
|
||||
*
|
||||
* Authenticator (optional): When the NTP authentication mechanism is
|
||||
* implemented, this contains the authenticator information defined in
|
||||
* Appendix C.
