    Wouldn't it make more sense for the endtime to be returned in the same
    format (relative/absolute) as the original timer was specified? That
    way an application can set a new timer for "timeout + SLEEPTIME" and on
    average it will be reasonably accurate.

    In the proposed method, for endtime to be useful the app needs to check
    the current time, compare with the endtime, and figure out the delta.
    If you're going to force the app to do all that work anyway, the app may
    as well use absolute times.
