It actually may be easier to understand if you write a trivial case
statement at the sole calling site of this helper function, though.
In any case, would it really be essential to make sure that the
output shows a phony (or a seemingly real) datestamp for this test?
The primary thing you wanted to achieve by the "gmtime gave us NULL,
let's substitute it with an arbitrary value to avoid dereferencing
the NULL" change was *not* that we see that same arbitrary value
comes out of the system, but that we do not die by attempting to
reference the NULL, I think. Not dying is the primary thing we want
to (and we already do) test, no?
