Analysis Tips:
Tracks the last execution time of the 0th MRU position by using the last modified time of the registry key.
RecentDocs key lists the MRU position of each last execute file and includes the last modified time of the registry key. If multiple for the same extension are present, it will only track the last opened time of the 0th MRU position in the file extension registry key.
Time:
All registry key has a value called “LastWrite” time, which is similar to file’s last modification time. In fact, this value is a FILETIME structure, which is the same as file’s MAC (Modified, Accessed, Created) time (Tan, 2001). The FILETIME structure is a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 UTC (MSDN, 2005c)
