  • computeLastCycleBoundary

    public static long computeLastCycleBoundary(long currentTime,
                                NetworkPolicy policy)

    Compute the last cycle boundary for the given NetworkPolicy. For example, if cycle day is 20th, and today is June 15th, it will return May 20th. When cycle day doesn't exist in current month, it snaps to the 1st of following month.
