Linux does not keep track of the creation time of a file. So, it will not
work to have a program on Linux ask a file how long it's been since the file
was created. If you want that information, you'll have to store it elsewhere
somehow (and that generally only works if you created the file in the first

The modification time of the file is the time that the file was last changed
(which would be the creation time if it were only ever written to once, but
in the general case, it has no relation to the creation time at all). So,
you could use std.file.timeLastModified to find out if a file has been
changed within the last x number of days, but there is no way to find out
the creation time of a file by asking the filesystem.
