List of issues

	1.  Should time() return an implementation defined time
	    representation or should it return elapsed seconds
	    since midnight January 1 1970 GMT?

The current POSIX draft already states that it returns the latter; do
we want to change this?

	    If it does not return elapsed seconds, should the name "time"
	    (or the type name "time_t") be changed (so as to noisily break
	    existing code, rather than quietly breaking existing code?)

X3J11 also has "time" and "time_t", although since they're not
defining an OS standard they do not require "time_t" to be an
integral type representing seconds since the epoch.
