automatic macro variables

Hi,

I run the following code

%put _all_;
data _null_;
day= weekday("16DEC2008"d);
put day;
run;


The log below shows &sysday = Thursday and the put statement is
returning 3 which represents the correct day of week Tuesday. The
system date is correct and these are the very first statements run
when SAS is started. Is there anyway to reset &sysday ??
