The documentation for the lcb_durability_opts_st structure at this address: http://docs.couchbase.com/sdk-api/couchbase-c-client-2.4.3/group___l_c_b___e_n_d_u_r_e.html#structlcb___d_u_r_a_b_i_l_i_t_y_o_p_t_sv0
provides information on the different parameters of the durability poll.However it does not specify which unit is used for the "interval" attribute. Will request to make it clear.
