NTPTimeStamp ::= OCTET STRING(SIZE(8))
-- TEXTUAL-CONVENTION
--  Status
--    mandatory
--  Descr
--    NTP timestamps are represented as a 64-bit
--    unsigned fixed-point number, in seconds relative to
--    00:00 on 1 January 1900.  The integer part is in the
--    first 32 bits and the fraction part is in the last
--    32 bits.
--  Refer
--    D.L. Mills, 'Network Time Protocol (Version 3)',
--        RFC-1305, March 1992, Section 3.1

NTPLeapIndicator ::= INTEGER {
        -- enum value of zero may cause problems
        noWarning(0),
        addSecond(1),

        alarm(3)
        }
-- TEXTUAL-CONVENTION
--  Status
--    mandatory
--  Descr
--    This is a two-bit code warning of an impending leap
--    second to be inserted in the NTP timescale.  The bits
--    are set before 23:59 on the day of insertion and reset
--    after 00:00 on the following day.  This causes the
--    number of seconds (rollover interval) in the day of
--    insertion to be increased or decreased by one.  The two
--    bits are coded as below,
--    00, no warning
--    01, last minute has 61 seconds
--    10, last minute has 59 seconds
--    11, alarm condition (clock not synchronized)
--  Refer
--    D.L. Mills, 'Network Time Protocol(Version 3)',
--        RFC-1305, March 1992, Section 3.2.1

NTPSignedTimeValue ::= OCTET STRING(SIZE(4))
-- TEXTUAL-CONVENTION
--  Status
--    mandatory
--  Descr
--    The time in seconds that could represent signed
--    quantities like time delay with respect to some
--    source.  This textual-convention is specific to 
--    implementation of NTP where 32-bit integers are used
--    for such quantities.  The signed integer part is in
--    the first 16 bits and the fraction part is in the
--    last 16 bits.
--  Refer
--    D.L. Mills, 'Network Time Protocol (Version 3)',
--        RFC-1305, March 1992, Sections 2,  3.2.1

NTPUnsignedTimeValue ::= OCTET STRING(SIZE(4))
-- TEXTUAL-CONVENTION
--  Status
--    mandatory
--  Descr
--    The time in seconds that could represent unsigned
--    quantities like maximum error of the local clock
--    with respect to some source.  This textual-convention
--    is specific to implementation of NTP where
--    32-bit integers are used for such quantities.  The
--    unsigned integer part is in the first 16 bits and the
--    fraction part is in the last 16 bits.
--  Refer
--    D.L. Mills, 'Network Time Protocol (Version 3)',
--        RFC-1305, March 1992, Sections 2, 3.2.1

NTPStratum ::= INTEGER(0..255)
-- TEXTUAL-CONVENTION
--  Status
--    mandatory
--  Descr
--    Indicates the stratum of the clock.  The stratum
--    defines the accuracy of a time server.  Higher the
--    stratum, lower the accuracy.
--    0, unspecified
--    1, primary reference (e.g., calibrated atomic clock,
--       radio clock)
--    2-255, secondary reference (via NTP)
--  Refer
--    D.L. Mills, 'Network Time Protocol (Version 3)',
--        RFC-1305, March 1992, Section 2.2

NTPRefId ::= OCTET STRING(SIZE(4))
-- TEXTUAL-CONVENTION
--  Status
--    mandatory
--  Descr
--    The reference clock identifier.  In the case of
--    stratum 0 (unspecified) or stratum 1 (primary
--    reference source), this is a four-octet,
--    left-justified, zero-padded ASCII string as defined
--    in RFC-1305.  In the case of stratum 2 and greater
--    (secondary reference) this is the four-octet Internet
--    address of the peer selected for synchronization.
--    
--    Some examples of stratum 0 identifiers are,
--    DCN, DCN routing protocol
--    NIST, NIST public modem
--    TSP, TSP time protocol
--    DTS, Digital Time Service
--    
--    Some examples of stratum 1 identifiers are,
--    ATOM, Atomic clock (calibrated)
--    VLF, VLF radio (OMEGA,, etc.)
--    LORC, LORAN-C radionavigation
--    GOES, GOES UHF environment satellite
--    GPS, GPS UHF satellite positioning
