How to time stamp the name (name + yyyymmdd) of an external csv file?

Hi,

I’d like to create an external file in order to export a csv file in an Oracle file share. However we must force the name of the exported file but I’d like to add the date time into this name when it’s cerated in the file share (and in the archive file share).

Is it possible in standard, if yes how to do it please?
