Yes. That is not to oversee, but I oversaw it, because I wanted to oversee it. For lazyness I use snprintf to fill the mtime field of a component of a v7 tar file I generate: snprintf(&hd[136],12,"%011lo", time(NULL)); This was not a problem in FreeBSD, where I wrote the program. But when I compiled it in OpenBSD, I got an error: time(NULL) is long long, lo is only long. I thought (without thinking too much) that this is because sizes are different, and I saw the included files (without seeing too much) and found a (false) explanation. Back to tar files: there is place for 11 octal digits, that is only twice the time you can count with 32 bits, in years: 2^33/(60*60*24*365.25*2)=136.09930083403047126524 Also not too much. Is it not a better solution to begin a new epoch every 68.05 years? We can do a big celebration at the beginning of each new epoch. Rod.
