you can view times and dates that files were modified or changed in windows.....date/time options are usually OS specific and programs use the OS clock to sync usually if I'm not mistaken...so you proposal wont work for broadcasting transaction history to a chain unless all odes are set to the same time....
anyway...in folder options there is an option to view all dates and times of all files and when they were lat viewed /changed
A File Time is a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC). Conversion from this internal format to a format more suitable for human interpretation is performed by the Windows system call, which extracts the year, month, day, hour, minutes, seconds and milliseconds from the timestamp data. NTFS file system stores time values in UTC format, so they are not affected by changes in timezone or daylight saving time.
