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

     This class contains the times at which a time series is observed
     and relates those dates to their location in the sample, i.e. the
     number of observation they are related to.

_S_l_o_t_s:

     '_i_n_p_u_t': Object of class '"numeric"': either the year and season
          of an observation provided as input or the location in the
          sample (observation) of a date provided as the input.

     '_o_u_t_p_u_t': Object of class '"matrix"': either the location in the
          sample of a date specified in 'input' or the date related to
          the observation specified in 'input'. the year and the
          season.

     '_w_t_s': Object of class '"ts"': the univariate time series.

     '_y_s': Object of class '"matrix"': the year and season of an
          observation.

     '_o_b_s': Object of class '"matrix"': the location in the sample of a
          date specified by the year and the season.

     '_M_y_s_o': Object of class '"matrix"': a matrix containing the dates
          and their locations in the sample at which the time series is
          observed.

_M_e_t_h_o_d_s:

     _a_s._n_u_m_e_r_i_c 'signature(x = "vdate")': Coerce an object of class
          `vdate' to a `numeric'.

     _s_h_o_w 'signature(object = "vdate")': Report the date to which a
          given observation is related to and vice versa.

     _s_t_e_p_d_a_t_e 'signature(object = "vdate")': Returns the date `x' times
          ahead in the sample. If that date is out of sample a message
          is generated.
