Assassins creed 3 was the first game in the series I played and the best in my opinion . It really got me into the entire series and I still follow it today . For free roam , AC 4 is the best . It has a massive map that spans over many islands in the Carribean , three cities , and some smaller towns . <| sep |> Someone has been planning on how they were going to quit <| sep |> I have to say you are wrong . The length of a second is not given by the length of our day . According to the scientific definition a second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom . Now , those transitions of the Cs atom are EXTREMELY precise and constant . There are devices called atomic clocks , which use that definition to measure time with an error of only 109 seconds in a day . These atomic clocks are EXTREMELY precise and they are what it is used to calibrate ALL clocks in the world . If a day would ' ve been 19 hours instead of 24 , scientists would ' ve noticed . Easily . So unless all scientists in the world are in on a huge conspiracy , you are wrong . Also , if the length of a second would ' ve changed , all other units of measure that are time dependent would ' ve changed as well . For example , the metre is defined as 1299 792 458 of the distance travelled by light in a second . In conclusion , a metre should ' ve been shorter as well if seconds are shorter . Another thing that needs to be mentioned is that one mississippi , two mississippi , or one one thousand , two one thousand was never a very precise way of measuring time . It is only a method you can use to roughly measure time when you don ' t have a timer or a clock at hand . They are not to be taken as an international standard .
