SAS intck函数返回错误

Question

无法弄清楚为什么intck函数返回错误的日期。 有什么线索吗？ 谢谢！

data b;    
   WeddingDay='14FEB2000'd;    
   Today='28MAR2000'd;    
   daysMarried=INTCK('day',WeddingDay,today());
   format WeddingDay Today date9.;
run;

proc print data=b; run;

1 14FEB2000 28MAR2000 5659

Answer 1

使用INTCK函数计算两个日期之间的天数。

data want;
   WeddingDay = '14FEB2000'd;
   Today = '28MAR2000'd;
   daysMarried = INTCK('day',WeddingDay,today);
   format WeddingDay Today date9.;
run;
