Incorrect Last Modified Time for File Is Returned by Query Information SMB (267913)

SYMPTOMS

When you query the last modified date of a file stored on a Windows NT-based server, an incorrect date may be returned. If you then use this value to manually update the last modified date of the file on the server, the incorrect date can end up being permanently applied to the file.

CAUSE

This behavior occurs because the Query File Information Server Message Block (SMB) only returns a 32-bit value for the last modified time. However, the NTFS file system stores the last modified time internally as a 64-bit value. When the SMB request is processed on the server, it returns the low 32 bits of this 64-bit time instead of converting it to a valid 32-bit value.
