Get hour and minutes of the (current time minus 20 second) into macro variables?

[hhchenfx]

Hi,

I want to put hour and minute of the time 20 second before current time into macro variable.

The code below might convey my idea better.

Can you please help?

Thanks,

HHC

%let now=%sysfunc(time()       MINUS 20 SECOND);
%let hh=%sysfunc(hour(&now),z2.);
%let mm=%sysfunc(minute(&now),z2.);

%put &hh &mm;

Have you tried

%let now = %sysfunc(time() ) - 20;

The other statements probably figure out to perform the math without even adding %eval
