2. Automatic Macro variables are those variables that are invoked automatically when a SAS job or session is started.
Date (SYSDATE or SYSDATE9) character value representing the date
SYSDATE uses the two-digit year (i.e., 11NOV15)
%put My SAS Session started on: &sysdate (two-digit year);
My SAS Session started on: 09NOV15 (two-digit year)
SYSDATE9 uses the four-digit year (i.e., 11NOV2015)
%put My SAS Session started on: &sysdate9 (four-digit year);
My SAS Session started on: 09NOV2015 (four-digit year)
Day (SYSDAY) day of the week (i.e., Wednesday)
%put My SAS Session started on this day of the week: &sysday;
My SAS Session started on this day of the week: Monday
Time (SYSTIME) the time (24 hr) (i.e., 14:30)
%put My SAS Session started at this time of day: &systime (24 hour format);
My SAS Session started at this time of day: 10:57 (24 hour format)

3. Date Day of the Week Current Time
timeAmPm8.0
Creating Current macros for date, day and time are easy and may be preferred. Especially if a batch job, or session, may run over night, or if you are interested in version output. The date and time the code was invoked can be captured:
Date
%Put The date today is: %sysfunc(date(),date9.);
The date today is: 09NOV2015
Day of the Week
%Put The day of the week is: %sysfunc(date(),downame9.);
The day of the week is: Monday
Current Time
%Put Current Time is: %sysfunc(time(),timeAmPm8.0);
Current Time is: 6:29 PM

4. Adding the date to: Filename DataFile
ODS PDF FILE= "C:\Users\scot.BIOSTAT\SYSDATE_EXAMPLE\MyOUTPUT_&sysdate9..PDF“;
DataFile
Data MyLib.MyData_&sysdate9; Set A; Run;
