2020 bug in date$ function?

[alincon]

I input 063020 to the date$ function and get back 06/30/1920 instead of the expected 06/30/2020.
The help file says if the first two digits of the year  are omitted, '20' is assumed.
Is it me, or is there a bug in the date$ function?

You likely using it wrong

d = date$("06/30/20")
print date$(d)

results in 06/30/2020

Same is
print date$(date$("06/30/20"))

I tried year from 00 to 99 - got back year from 2000 fo 2099

It may be the slashes, but 063019 works without slashes. Years greater than 2019 do not work w/o slashes, seems to me.

Oops! I had forgotten about this code in my program.
function dat$(d$)
   if len(d$) < 7 then  d$ = mdcySlash$(d$)
   d = date$(d$)
   dat$ = str$(d)
   end function

function mdcySlash$(a$)   'mon day century year
   mdcySlash$=left$(a$,2) + "/" + mid$(a$,3,2) + "/" + str$(19 + (right$(a$,2) < "20")) + right$(a$,2)
   end function
