!------------------------------------------------------------------------------


    DESCRIPTION       "This relation holds all clock updates that were sent
                       to the Space Telescope.  These clock updates are used
                       for command synchronization and to decipher the data.
                       To date the clock has ticked eight times a second with
                       no drift;  it was updated quarterly, we now are updating
                       it weekly.  Clock updates originate at Goddard.

                       PODPS populates this relation whenever they receive
                       the data in a science observation.  The update is 
                       automatic with data processing.
                       SMS/Generate uses this relation for SMS times."

!------------------------------------------------------------------------------



    FIELD  ref_ut_lo
        TYPE            R8
        DESCRIPTION     "This is the low order bits of the reference UT time.
                         Combined with the high order bits a VMS system call
                         will give a more reconizable time format."
    END_FIELD



    FIELD  ref_ut_hi
        TYPE            R8
        DESCRIPTION     "This is the high order bits of the reference UT time." 
    END_FIELD



    FIELD  ref_clock_ct
        TYPE            I4
        DESCRIPTION     "This is the number of clock counts (ticks) since
                         the defined zeroth tick.  This times the clock rate 
                         gives the number of seconds since the clock was zero.
                         This value will roll around periodically since the 
                         spacecraft has a fixed number of bits for it."
    END_FIELD



    FIELD  ref_clock_rt
        TYPE            R8
        DESCRIPTION     "This is the clock rate, how often it ticks."
    END_FIELD



    FIELD  ref_clock_dr
        TYPE            R8
        DESCRIPTION     "This is the clock drift rate or how it gains or loses
                         time."
    END_FIELD



    FIELD  trans_time
        TYPE            R8
        DESCRIPTION     "This is when PODPS loaded the latest time record."
    END_FIELD



    FIELD  ascii_ref_ut
        TYPE FULL_SOGS_CHAR_TIME_TYPE
        DESCRIPTION     "This is an ASCII representation of the ref_ut time
                         fields for user's viewing data directly."
    END_FIELD
