or, when *your program* calls OSWORD, overwrite "19" with "20".
My prefered method is to actually write the code that calls OSWORD
correctly!
  Call OSWORD
  year%=1900+?X%-100*(?X%<81)
 
correctly reads the time with the year ranging from 1981 to 2080.

Again, the result of lazy programmers refusing to call the API correctly.
 
  Call FSOp
  year%=X%?5 DIV 16+(X%?4 AND&E0) DIV 2
  date%=X%?5 AND 15
  month%=X%?4 AND 31
 
correctly reads NetFS style dates with the year ranging from 1981 to 2108.
