[Spice_announce] IMPORTANT: New Leap Second and New SPICE LSK

[Charles H. Acton]

The International Earth Rotation and Reference Systems Service (IERS) 
has announced there will be a new leap second effective January 1, 
2009. NAIF has created new versions of the leapseconds kernel (LSK) 
to accommodate this new leap second:   naif0009.tls for Unix, Linux 
and OSX, and naif0009.tls.pc for Windows. These new leapseconds 
kernels are available from the Generic_kernels area of the NAIF 
server.

The new LSK appropriate for your platform may be downloaded and used 
to replace the naif0008 LSK at your convenience, but no later than 
December 31, 2008. Using the new LSK will NOT affect time conversions 
involving dates prior to Jan 1, 2009, but will affect time 
conversions involving dates after Jan 1, 2009.
