DOCUMENT:Q123717 07-FEB-2002 [winnt] TITLE :Windows NT Backup Writes Incorrect Times To Log PRODUCT :Microsoft Windows NT PROD/VER::3.1,3.5 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server versions 3.1, 3.5 - Microsoft Windows NT Workstation versions 3.1, 3.5 - Microsoft Windows NT Advanced Server, version 3.1 ------------------------------------------------------------------------------- SYMPTOMS ======== Windows NT Backup writes incorrect times (one hour late) to its log when the time zone is not with the United States. CAUSE ===== GetCurrentDate() in \PRIVATE\UTILS\NTBACKUP\SRC\DATETIME.C uses the C- Runtime call localtime() to get the current time (instead of the Win32 API GetLocalTime()). Localtime() calls tzset() to determine the time zone and daylight saving settings. Tzset doesn't take the real daylight saving information from GetTimeZoneInformation into account. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT Workstation and Windows NT Server version 3.5. This problem was corrected in the latest U.S. Service Pack for Windows NT version 3.5. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces): S E R V P A C K Additional query words: prodnt 3.50 USA us ====================================================================== Keywords : Technology : kbWinNTsearch kbWinNTWsearch kbWinNT350search kbWinNTW350 kbWinNTW350search kbWinNTW310 kbWinNTSsearch kbWinNTS350 kbWinNTS310 kbWinNTAdvSerSearch kbWinNTAdvServ310 kbWinNTS350search kbWinNTS310search kbWinNT310Search kbWinNTW310Search Version : :3.1,3.5 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
