Hi, > printf "<time>1999-09-09T%02d:%02d:%02dZ</time>\n",$sec/3600, > ($sec/60)%60,$sec%60; Please use the unix epoch (Jan 1st, 1970? Maybe just cast 0 into a time ;) for this, as it is commonly used as bogus time and so it will be easier to fix the database once the server finally understand untimed gpx files. Ciao, Imi
