A 1994 computer, running Microsoft Word, I think on some version of DOS, displayed on its monitor a 2 line message, saved as 'message.doc'. My questions are: 1. would the technician checking the machine have been able to know that the clock had reverted at poweron to 01 January 1980, because of the dead mainboard battery, by minimizing Word, if that was possible with that old display, or by other method, could he have known that the clock had reverted to the old date? 2. would the technician have been able to know the exact time at which the timestamp was applied to 'message.doc'? 3. would the person who typed the message have been able to alter the timestamp of the .tmp file that was created? (that .tmp file apparenty was automatically saved by Word, and not deleted by Word, because Word, instead of being 'exited', was crashed when the computer was deliberately 'crashed', about 5 minutes after 'message.doc' was saved, and the .tmp file was timestamped 12:00:30 01 January 1980.) A blurry photo of the screen is at http://superfly.co.nz/bain/pc.jpg and the computer, with no mouse obvious to me is in a better photo at http://superfly.co.nz/bain/alcove.jpg Thanks for any clues.
