There are no query language operators or functions that select points based on ordinality. The best current solution to your need is to use a CQ, which won't introduce noticable additional storage or load, unless you are running on a very low power device.
CREATE CQ... SELECT FIRST(value) AS "60th_point" INTO bar FROM foo GROUP BY time(1m), * END That will store the point from xx:xx:00 in the new "bar" measurement.
