Hi Tobi, Here is a patch. I added a int instead of a bool as it seems that int is used for booleans everywhere in the code. I called fct1 time_clean. I tried to catch as much formatter as possible but of course as strftime() formatter's are not the same depending of OS my code can't handle this very well... I hope my code is not too much ugly.. I did not practice C for a while.
