Update
1999-07-01 Cristian Gafton <gafton@redhat.com> * time/strptime.c (strptime): Initialize the tm struct first to avoid returning bogus results on incomplete data. (strptime_internal): day_of_the_week() requres bith tm_mon and tm_mday to be initializaed. Computer them first if they are not given. (strptime_internal): (have_mon, have_mday): New variables.
