_D_e_s_c_r_i_p_t_i_o_n:

     'Sys.time' and 'Sys.Date' returns the system's idea of the current
     date with and without time.

_U_s_a_g_e:

     Sys.time()
     Sys.Date()

_D_e_t_a_i_l_s:

     'Sys.time' returns an absolute date-time value which can be
     converted in various time zones and may return different days.

     'Sys.Date' returns the day in the current timezone.

_V_a_l_u_e:

     'Sys.time' returns an object of class '"POSIXct"' (see
     DateTimeClasses).  On some systems it will have sub-second
     accuracy, but on others it will increment in seconds. On systems
     conforming to POSIX 1003.1-2001 the time will be reported in
     microsecond increments.

     'Sys.Date' returns an object of class '"Date"' (see Date).

_S_e_e _A_l_s_o:

     'date' for the system time in a fixed-format character string; the
     elapsed time component of 'proc.time'  for possibly finer
     resolution in changes in time.

     'Sys.timezone'.

_E_x_a_m_p_l_e_s:

     Sys.time()
     ## print with possibly greater accuracy:
     op <- options(digits.secs=6)
     Sys.time()
     options(op)

     ## locale-specific version of date()
     format(Sys.time(), "%a %b %d %X %Y")

     Sys.Date()
