It also uses alarm semantics rather than delay semantics, which means
it's susceptible to time shifts. Assuming different ST_ALARM and

If you take a look at the postings dated back in April, you will find
that such API already exists, it's POSIX::times. There is no need to
reinvent the wheel.
Yeah, that's what I'd

Is there any particular advantage of replacing ST_TIME w/ ST_ALARM?
ST_TIME uses the old system time based semantic. Isn't what we are
trying to do here simply to add a delay based semantic? How about
keeping ST_TIME and adding ST_DELAY?
so, let me get this
