## @deftypefn {} {} clock ()
## Return the current local date and time as a date vector.
##
## The date vector contains the following fields: current year, month (1-12),
## day (1-31), hour (0-23), minute (0-59), and second (0-61).  The seconds
## field has a fractional part after the decimal point for extended accuracy.
##
## For example:
##
## @example
## @group
## fix (clock ())
##      @result{} [ 1993, 8, 20, 4, 56, 1 ]
## @end group
## @end example
##
## @code{clock} is more accurate on systems that have the @code{gettimeofday}
## function.
## @seealso{now, date, datevec}
## @end deftypefn
