I think we have lived with relative timeouts for so long, it would be unusual to change now. select(2), poll(2), epoll_wait(2) all take relative timeouts.

I'm not talking about always using absolute timeouts.

I'm saying the timeout parameter should be a struct timespec* and then the flags word could have a flag meaning "this is an absolute timeout". I.e., enable both uses,, even make relative timeouts the default. This is what the modern POSIX interfaces do, too, see clock_nanosleep.
