/**
 * Determines the starting point ("anchor") for a period.
 *
 * To produce repeatable rotation points in time, the period is "snapped" to a "grid" of time.
 * For example, an hourly index rotation would be anchored to the last full hour, instead of happening at whatever minute
 * the first rotation was started./*from   ww  w . java  2  s. c om*/
 *
 * This "snapping" is done accordingly with the other parts of a period.
 *
 * For highly irregular periods (those that do not have a small zero component)
 *
 * @param period the rotation period
 * @return the anchor DateTime to calculate rotation periods from
