To learn more about auditing local file and folder access in Windows 2000, check out this TechRepublic article.Īll the 32-bit Windows operating systems track all three time stamp values described above, and there are three ways you can view this information: individually for each file through its properties, for all files and subdirectories in a directory through Explorer, or at the command line. To do so, you must turn on auditing in group policy and enable auditing for the particular file(s) or folder(s). One solution is to use object access auditing to write an event to the Security log whenever someone accesses a file or other object. This can be a problem when it’s important to know whether a file has been read since it was modified. In Windows XP and other NT-based operating systems, you’ll find that the modified and accessed dates/times are usually the same, even if you open, read, and close the file. Time/Date Accessed: This is supposed to show the last time the file was accessed, but experience proves that opening and reading a file without making changes does not immediately change this time stamp in Windows XP (this is because of the variance in resolution time mentioned earlier).Neither does opening the file without making any changes to it. Renaming the file doesn’t change the modification time stamp. Whenever the contents of the file are changed, or files are added to or deleted from a directory, this time stamp changes. Time/Date Modified: This is also called the Last Written date.(Note: It is possible to end up with a file that has a modification time that’s earlier than its creation time when you make a new copy of a file.) Moving a file or simply renaming it does not create a new file, and thus does not give the file a new creation time stamp. If you make a new copy of a file and save it to a different location, it is treated as a new file and a new creation time stamp is set. Time/Date Created: When you create a new file or directory, this value is set and does not normally change (unless you deliberately change it).Naval Observatory.Īll Windows file systems record the same three values: For more information, check out this Web page of the U.S. UTC, or Universal Time Coordinate, is basically the same as Greenwich Mean Time (GMT) and is determined by very precise atomic clocks at time labs in various parts of the world. FAT uses the local time that is set in your operating system’s regional settings, but NTFS uses Universal Time Coordinate (UTC) to record times (so as not to be affected by time zones and daylight savings time).
Another difference is in the way the time is recorded. The major difference is in the resolution time, which can vary from 10 milliseconds for “create time” on FAT-formatted files to one hour for “access time” on NTFS-formatted files. The Windows operating systems handle time stamping differently depending on the file system in use, since this is actually a file system functionality.

In this Daily Drill Down, we will look at how the Windows operating systems handle time stamps, how to view the time stamps on files and directories, and why and how time stamps are changed. There are also a large number of programs available that are designed for manipulating time stamps.

This error can be caused by software programs or inadvertently or deliberately by a user to create a false time stamp. This could be because the computer’s system clock has been incorrectly set. For various reasons, the dates and times recorded may be inaccurate.
However, the time stamps displayed by the operating system are by no means foolproof. Modern Windows operating systems (Windows 9x through XP) keep records of these three values for each file and directory. In many situations, ranging from business transactions to computer forensics investigations, it can be important to know the date and time a file was created, accessed, or changed. Understand how the Windows operating systems handle time stamps, how to view the time stamps on files and directories, and why and how time stamps are changed.
