A tool that allows the user to modify all four [[NTFS]] timestamps (MACE) values. Developed by [[James C. Foster]] and [[Vincent Liu]]. Although this program is designed to frustrate forensic analysis, it should be noted that its use can be easily detected. Because the program deletes all time stamp information, it is a dead giveaway that something is amiss on the system. Any normal system has at least ''some'' timestamp information. The total absence of such is a dead giveaway that a user has tried to hide something.
