WPS: Check for theoretical gmtime() failure

Browse source 
In theory, gmtime() could return NULL if the year value would not fit
into an integer. However, that cannot really happen with the current
time() value in practice. Anyway, clean up static analyzer reports by
checking for this corner case.
