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

     Extract and encode the times the first and last obser-
     vations were taken. Provided only for compatibility
     with S version 2.

_U_s_a_g_e_:

     start(x, ...)
     end(x, ...)

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

       x: a univariate or multivariate time-series, or a
          vector or matrix.

     ...: extra arguments for future methods.

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

     These are generic functions, which will use the `tsp'
     attribute of `x' if it exists.  Their default methods
     decode the start time from the original time units, so
     that for a monthly series `1995.5' is represented as
     `c(1995, 7)'. For a series of frequency `f', time
     `n+i/f' is presented as `c(n, i+1)' (even for `i = 0'
     and `f = 1').

_W_a_r_n_i_n_g_:

     The representation used by `start' and `end' has no
     meaning unless the frequency is supplied.

_S_e_e _A_l_s_o_:

     `ts', `time', `tsp'.
