The trees were scored with a ledge called a “box” to collect the sap.
By 1929, all major countries in the world had accepted time zones. In the present day, UTC offsets divide the world into zones, and military time zones assign letters to the 24 hourly zones, similarly to Fleming's system. [29] Fleming was also interested in global calendar reform. He met Moses B. Cotsworth in 1908 when Cotsworth visited Ottawa.
