it
test case to demonstrate failure in parsing %Z format

And unfortunately the way it ignores the timezone name makes strptime() una=
ble
to parse names that are not delimited by white space.

For example strptime(, "%Z/",) will return NULL, because the trailing slash
will be consumed as the timezone name.

This corner case makes strptime() unable to parse strftime() output:

    strftime() produced "GMT/"
    strptime() failed to parse "GMT/"
