_D_e_s_c_r_i_p_t_i_o_n:

     The function obtains the times at which track values occur.

_U_s_a_g_e:

     tracktimes(trackdata) 

_A_r_g_u_m_e_n_t_s:

trackdata: An EMU trackdata object, or a matrix  of track values
          obtained at a single time point using dcut() 

_D_e_t_a_i_l_s:

     Every $data value in a trackdata object is associated with a time
     at which it occurs in the utterance. This function returns those
     times.
