Bug #6728: mktime / date misbehaving around 1964 nd earlier

From: david@broadowler.co.uk Operating system: Linux 2.2.14 (Redhat6.2) PHP version: 3.0.16 PHP Bug Type: Misbehaving function Bug description: mktime / date misbehaving around 1964 nd earlier Date functions erratic in 1960's - perhaps too many drugs around at the time ? Causes me grief with age validation routines. Checked reports - can't see similar report. All kit local - Apache and PHP build from source trees, no modifications to source (I wouldn't dare!) Script to cause failure: <?php $d4=mktime(0,0,0,09,01,1961);$d4s=date("D d F Y", $d4); echo "Date was $d4 [$d4s] <br>"; ?> result (should be sep 1st 1961) is Date was -286675200 [Thu 01 December 1960] Configure Line: Configure command: ./configure '--with-apxs=/local/apache/bin/apxs' '--with-apache=/tmp/apache' '--with-gd=no' '--with-mysql' '--enable-sysvshm=yes' '--enable-sysvsem=yes' '--with-config-file-path=/local/apache/conf' '--enable-track-vars=yes' '--enable-force-cgi-redirect=yes' '--enable-short-tags=no' Apache Details: Apache Version: Apache/1.3.12 Apache Release: 10312100 Apache API Version: 19990320 Loaded modules: mod_php3, mod_setenvif, mod_so, mod_unique_id, mod_usertrack, mod_headers, mod_expires, mod_cern_meta, mod_proxy, mod_digest, mod_auth_dbm, mod_auth_anon, mod_auth, mod_access, mod_rewrite, mod_alias, mod_userdir, mod_speling, mod_actions, mod_imap, mod_asis, mod_cgi, mod_dir, mod_autoindex, mod_include, mod_info, mod_status, mod_negotiation, mod_mime, mod_mime_magic, mod_log_config, mod_env, mod_vhost_alias, http_core
