Awake in itself is intuitive in some contexts, but it doesn't seem to describe the semantics you want in this case. First of all it's not obvious that it's related to syscalls. Secondly it doesn't really mean the process is guaranteed to awake after the specified time - if the syscall doesn't block or finishes faster, the process might well stay sleeping at the alleged awaking time. Someone who doesn't know all the details will easily get the wrong idea.
