Those are tests, which aren't run during setup. Besides that, there's no 
(find-seconds 0 0 0 1 5 1970) in "low-level-tests.rkt".

I scanned through the plot documentation and found this, though:

   (parameterize ([plot-x-label      "Near x axis"]
                  [plot-y-label      "Near y axis"]
                  [plot-z-label      "Near z axis"]
                  [plot-x-ticks      (date-ticks)]
                  [plot-y-ticks      (time-ticks)]
                  [plot-z-ticks      (fraction-ticks)]
                  [plot-x-far-label  "Far x axis"]
                  [plot-y-far-label  "Far y axis"]
                  [plot-z-far-label  "Far z axis"]
                  [plot-x-far-ticks  (linear-ticks)]
                  [plot-y-far-ticks  (currency-ticks)]
                  [plot-z-far-ticks  (log-ticks #:base 2)])
     (plot3d (lines3d '(#(1 1 1) #(40000000 4 4)) #:style 'transparent)
             #:angle 45 #:altitude 50
             #:title "Axis Names and Tick Locations"))

One of the tick labels on the near x axis is "1970-05". I don't remember 
exactly how the tick layout and formatting code works, but it's very 
possible that it uses `find-seconds' with the arguments 0 0 0 1 5 1970 
to position that label.

BTW, it's not January 5, but May 1. Is that a valid date on your 
machine? Also, does either (find-seconds 0 0 0 1 5 1970 #f) or 
(find-seconds 0 0 0 1 5 1970 #t) fail in Racket?
