Is the time stamp of an event important?
Time of an Event Critical to most computer investigations Basis of timeline analysis However, is not an area that is well investigated, written and published. In fact, what is written can be misleading and inaccurate. Which puts the impetus on the individual examiner to conduct their own testing for now. 4.
How are timestamps stored in a file system?
In an NTFS file system, timestamps are stored as 8-byte file time values which represent the number of 100-nanosecond intervals that have elapsed since 12:00 A.M. January 1, 1601 (MSDN Article on File Times). Consequently, NTFS timestamps have 100 nanosecond (0.1 microsecond) precision.
