Apparently done by Peter in the meantime.

The idea was to return 100 in the test whether the format can be read based on the extension.
I.e. if you have .dat and you put here *.dat, the ASCII source will always be called for this file.
In the future, we could extend this to associate all properties (header, formatting, etc...) to a name, and a file extension.
There is a bug open on that: http://bugs.kde.org/show_bug.cgi?id=216744

Hum, apparently there is no file creation date on Unix indeed!
I guess our best approach here would be to estimate it as QFileInfo::lastModified() - (QDateTime(last sample) - QDateTime(first sample)),
i.e. assume the lastModified is the date of the last sample and substrat the time difference between the last and first sample to get the time of the first sample.
Should give reasonably good results...
