### Question:
Utils { public static long toUnixTime(long javaTime) { return javaTime / 1000; }  static String longToTimePeriod(long msec); static SecureRandom getRandom(); static String getNodeIdShort(String nodeId); static long toUnixTime(long javaTime); static long fromUnixTime(long unixTime); @SafeVarargs static T[] mergeArrays(T[]... arr); static String align(String s, char fillChar, int targetLen, boolean alignRight); static String repeat(String s, int n); static void showErrorAndExit(String message, String... messages); static void showWarn(String message, String... messages); static String sizeToStr(long size); static void sleep(long ms); @Deprecated static long time();  }### Answer:
@Test public void toUnixTime() { Assert.assertEquals(1, Utils.toUnixTime(1000)); }
