From source file:com.androidinspain.deskclock.Utils.java

/**
 * Given a point in time, return the subsequent moment any of the time zones changes days.
 * e.g. Given 8:00pm on 1/1/2016 and time zones in LA and NY this method would return a Date for
 * midnight on 1/2/2016 in the NY timezone since it changes days first.
 *
 * @param time  a point in time from which to compute midnight on the subsequent day
 * @param zones a collection of time zones
 * @return the nearest point in the future at which any of the time zones changes days
 *//*w  ww.  j a  va2  s.  c o  m*/
