FPNW Returns Time Stamp with 60 Seconds to ClientsLast reviewed: November 18, 1997Article ID: Q166421 |
The information in this article applies to:
SYMPTOMSWhen you save a file where the seconds portion of the time stamp is 59 to a folder on a Windows NT server, File and Print Services for NetWare (FPNW) clients see the seconds portion as 60 instead. Some applications may return error messages stating that the file is invalid or corrupt. This problem has occurred with Microsoft Project 4.0.
CAUSEWhen calculating the time stamp, FPNW server rounds up odd second time stamps but does not propagate the carry. For example, 16 minutes and 59 seconds should be rounded up to 17 minutes and 0 seconds (and not 16 minutes and 60 seconds).
MORE INFORMATIONThe MS-DOS FAT file system and the NCP protocol are using two bytes to represent both a date and time stamp. Of the 16 bits of the time stamp, 5 bits are reserved for the hour (0-23,) 6 for the minute (0-59,) and 5 for the second (0-29) part of the time stamp. There can only be time stamps in two seconds granularity. This is the reason why FPNW has to do this calculation. The fix now calculates the same way as the Server Message Block (SMB) server does.
RESOLUTIONObtain the hotfix mentioned below.
STATUSMicrosoft has confirmed this to be a problem in Windows NT version 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
