标题: a question about time() [打印本页] 作者: shiyiming 时间: 2012-8-2 22:40 标题: a question about time() data _null_;
t=time();
format t datetime22.2;
put t=;
run;
run the code above, and I got the following result:
t=01JAN1960:09:42:30.38
Question: As we know time() function will generate the current time of day, but the result t is 01jan1960, so, anyone can help or explain?
thanks!!!作者: shiyiming 时间: 2012-8-3 10:36 标题: Re: a question about time() time（）读的是时间的数据而没有读日期的数据，而datetime格式要求输出的是日期和时间，所以会出错作者: shiyiming 时间: 2012-8-3 11:11 标题: Re: a question about time() 问题在于格式设置上，由于t=time(); 仅仅提取的是时间数据，而在格式的设置上却要求输出
日期，所以sas系统就加上了，系统默认的初始日期。请看下面的代码：
[code:28lbem29]
data _null_;
t1=time();
t2=t1;
format t1 time. t2 datetime22.2;
put t1= t2=;
run;
[/code:28lbem29]
