SMART-1 SCLK File
===========================================================================

     This file is a SPICE spacecraft clock (SCLK) kernel containing
     information required for SMART-1 spacecraft on-board clock to UTC
     conversion.


Production/History of this SCLK file
--------------------------------------------------------

     This file was generated by the NAIF utility program MAKCLK, version
     3.5.2, from the most recent SMART-1 spacecraft SCLKvSCET file (see
     corresponding section of the description for the SCLKvSCET SFDU header
     and MAKCLK setup file).


Usage
--------------------------------------------------------

     This file must be loaded into the user's program by a call to the
     FURNSH subroutine

          CALL FURNSH( 'this_file_name' )

     in order to use the SPICELIB SCLK family of subroutines to convert
     SM1 spacecraft on-board clock to ET and vice versa.


SCLK Format
--------------------------------------------------------

     The on-board clock, the conversion for which is provided by this SCLK
     file, consists of two fields:

          SSSSSSSSSS:FFF

     where:

          SSSSSSSSSS -- count of on-board seconds

          FFF        -- count of fractions of a second with one fraction
                        being 1/65536 of a second
