Hi,

I found your reques inline with the current proposal n2497 contains already 
this overloading
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2497.html
    void sleep(const system_time& abs_t);
    template <class Duration>
        void sleep(const Duration& rel_t);

There is also a more recent proposal N2651-A Foundation to Sleep On- Clocks, 
Points in Time, and Time Durations
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2615.html
In it we found a proposal to update the thread library rename the sleep 
functions

    Threads
    The current time-related threading API is adapted to this proposal. An 
emphasis is put on ease of use, safety, efficiency, and     durability with 
respect to advancing technology over time.
    Summary of changes:
    The parameters of the time-related functions have been modified to match 
the time API in this proposal.
        sleep(rel_time) has been renamed to sleep_for(rel_time).
        sleep(abs_time) has been renamed to sleep_until(abs_time).

Particularly I prefer this renamming, but for compatibility purpose bouth 
shoul be implemented.

Best,

Vicente
