While I definitely agree this is one of the most basic things to > have, it's also not an area of the kernel that is easy to change. 64-bit clock_gettime / clock_settime instead of gettimeofday / settimeofday should avoid the need for the kernel to have a 64-bit version of struct timeval. (Userspace 64-bit gettimeofday / settimeofday would need to use a combination of the syscalls if the tz pointer is non-NULL.) -- Joseph S. Myers joseph@codesourcery.com
