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

     Extract and encode the times the first and last observations 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'.
