My problem is the following. In Org there is a function to create a PDF from an org file. That function displays an error message when a problem occured during PDF creation. To find out if a problem occured during creation, that function compares the time at the beginning of the processing and the last modification time of the PDF file. When the later is behind the former, the function displays an error message. The problem is when the directory of the PDF file is on a server, server current time can be different from client current time, and then the error can be wrongly displayed. One solution to correct the function can be to create a temporary file in the same directory as the PDF file and compare the times using creation time of the temporary file instead of local current time. So I wanted to know if there exists a function that can check a path and tells if its remote or local. -- Pascal Quesseveur pquessev@gmail.com
