respect nsec in TimeWithZone

Browse source 
when we pass fractional usec to Time methods we should use Rational
instead of Float because of accuracy problem

    Time.local(2011,6,12,23,59,59,999999.999).nsec
    # => 999999998

    Time.local(2011,6,12,23,59,59,Rational(999999999, 1000)).nsec
    # => 999999999
