How to get system date in R5Rs in Scheme/DrRacket

In DrRacket IDE, I was able to get the system date in the following manner when the language setting was 'Swindle':

(define currentMonth 0)
(let ((date (seconds->date (current-seconds))))
  (set! currentMonth (date-month date))
  )

Now, I need to do the same in R5Rs, but not sure how to. May I please seek your advise/help on this..

Thank you!

There is no date-time support in R5RS. The procedures current-seconds , seconds->date and date-month should be available in the R5RS implementation of PLTRacket as extensions.
