Also note that the subject of this thread is limited to "time.asctime
and time.ctime."  The other functions came into discussion only
because the year range checking code is shared inside the time module.
 If calling specific system functions such as strftime with tm_year <
0 is deemed unsafe, we can move the check to where the system function
is called.  No system function is called from time.asctime anymore and
time.ctime(t) is now time.asctime(localtime(t)).
