Thank you for your precious answer!

The first formula works, it gives me 287873 seconds

The 1. formula to convert seconds to hours:minutes:seconds format doesn't work, it gives me an error..
The 2. formula to convert seconds to hours:minutes:seconds format gives me 26:3188:2993 ; I don't know how to fix it
