Observe:

? (defun foo1 () #'bar1)
FOO1
? (defun foo2 () #'common-lisp::bar2)
FOO2
? (defun foo3 () #'common-lisp:bar3)

> Error: Reader error: No external symbol named "BAR3" in package #<Package "COMMON-LISP"> .

Note that FOO1 and FOO2 will both error at runtime.  CCL should have warned
when defining those functions as well.

The CLHS says: Universal time is an absolute time represented as a single non-negative integer---the number of seconds since midnight, January 1, 1900 GMT [...] Because universal time must be a non-negative integer, times before the base time of midnight, January 1, 1900 GMT cannot be processed by Common Lisp.

? (ENCODE-UNIVERSAL-TIME 0 0 19 31 12 1899) 0 ? (ENCODE-UNIVERSAL-TIME 59 59 18 31 12 1899) -1

The right thing to do would probably be to signal a type error.
