From: marcello at vezz dot it Operating system: Windows XP PHP version: 5.2.6 PHP Bug Type: Filesystem function related Bug description: filemtime reports time shifted by daylight saving hours
Description: ------------ I quote from Bug #40568: PHP filemtime/fileatime/filectime (and maybe stat itself) functions should use GetFileTime() Win32API (or GetFileAttributesEx()), not stat() to retrieve the actual times from files. Otherwise the returned time is shifted by one hour in some conditions. This (mis)behaviour is actually DOCUMENTED by Microsoft, so it does not qualify for "bogus - fix microsoft libraries" bug rejection -- Microsoft already fixed their documentation and even indicated that "This behavior is by design."
