A feature which would have widespread utility would be to use
the Windows "Date Created" information, available from Windows Explorer,
to implement a select-able mode
in which the actual Time-Of-Day is displayed in the VLC window progress bar,
instead of the time-displacement since the beginning of the file.
Some files could be 10 hours long, during which a specific event is known
to have occurred at a certain time of day.
Much of this type of viewing, and perhaps editing (VLC-Record), requires the user
to look at the Date Created, do some arithmetic on fingers thumbs and toes,
to derive the desired file displacement point.
(e.g. a goal, try or touchdown was scored in 39th minute).
If VLC developers find this full implementation too difficult,
a fallback implementation would be to allow the user to enter
the time-of-day of the beginning of the file from their keyboard from reading
their Windows Explorer display columns themselves, and
have the program allow the user to select "File Created time displacement display".
The user may have to explicitly configure their Windows Explorer display
to add the Date Created column, which is trivial.
This fallback implementation should be trivial.
