You probably have a problem in the substrate that ISOdate feeds on.

Offhand, I'd suspect an overrun problem. Some systems that represent
time as seconds since 1970 get in trouble in 2038, wouldn't they also
get in trouble from going more than 68 years backwards in time from
1970. Does it work if you replace 1901 with - say - 1910?

To see if the rest checks out, you could comment out that example in
the sources.
