This is great! We all have an opportunity to learn about events in history. There are so many defining moments in the history of the world we can learn from.
My post below is about the establishment of Standard Timezones and Daylight savings time which is something most of us experience or are accustomed to. It is also an important event in history that set the foundation of where we are today when it comes to our current observation the different time zones and DST.
Excellent @cloh76. The Calder Act, what a great topic! And today, history is repeating itself. In 1918 we received a global metric for Time. Perhaps in 2018, we'll receive a global metric for Currency!
Hopefully, Steem/SBD, Bitcoin, and Cryptocurrencies will be part of that global metric of currency. Wouldn't that be awesome!
