Date stamp and how to change on a doc.file

I am about as ignorant as they come in regard to computers......I recently learned that the date stamp on computer files/docs can be altered and that there is software that enables the user to alter it.

My question is; WHY would you want to alter a date stamp on a doc? Are there legitimate reasons for doing this?

I have concerns that some work related docs have been altered to protect certain individuals.

Thanks!

 

they can be altered, but any security admin will query actions which users used to alter file properties...Everything leaves a trace. Everything.

Now, someone would alter a date stamp to control the perception of time relating to said document or the completion time of said document. There are legitimate reasons (like grouping with a batch of other documents to make sorting easier --- other reasons are obvious: someone simply opened the file and resaved it, changing it automatically with a later date....but most weasels alter it to make docs appear that they came *before* they really did

Be careful. hope this helps.
