I installed the attached patch into Emacs master to try to fix this.
I'll CC: this to emacs-orgmode in the hopes that this won't get lost in
the next merge to Emacs master.

Subject: [PATCH] Port recent org-clock fix to POSIX time_t
* lisp/org/org-clock.el (org-clock-special-range):
Don't assume support for time_t values less than 0, or less than
-2**31 for that matter (Bug#27736).
