    :
    : Except it doesn't have to tick twice. Refer to
    : http://lkml.org/lkml/2009/1/7/78 in which I show that a time_t (what
    : time() returns) counts leap seconds (According to Bernstein this is what
    : UTC means), and using zoneinfo, the library processes leap seconds
    : correctly.

    This is *NOT* POSIX time_t. In order to be posix compliant, you can't
    do what Bernstein suggests. You can be non-complaint and deal it with
    zoneinfo.

    : I just realised that the Notes in man 2 time are confusing and probably
    : unnecessary. Suffice to say that (assuming correctly configured
    : zoneinfo) time() returns the number of seconds elapsed since start 1970.

    That's not POSIX complaint.
