SAS Home Documentation Watchouts Installation Software requirements Download


Please be aware that the data file containing the leap seconds used by SAS has been updated on April 24 2009 with the corresponding 2009 leap second. This affects only absolute timing analysis with data taken from January 1 2009 on. SAS 8 users interested in absolute timing analysis should therefore replace the file leapsecs.dat present in $SAS_DIR/lib/data/leapsecdata/ distributed with SAS 8.0 - The next SAS version (SAS 9, to be released in June) will contain the update - The file can be obtained here.

We are sorry for the inconveniences caused.
