### Question:
TimeUtils { public static long getSomeDayTime(int N) { Date now = new Date(); long time = now.getTime() / 1000 + N * 86400; time = time - time % 86400; return time; }  static String getTodayDaily(); static String getTodayDaily(int N); static String getDailyByTime(long time); static long getSomeDayTime(int N);  }### Answer:
@Test public void testGetSomeDayTime() { long time = TimeUtils.getSomeDayTime(0); assertTrue(time >= System.currentTimeMillis() / 1000 - 86400); assertTrue(time <= System.currentTimeMillis() / 1000 + 86400); }
