Krono Gallifreyan started a long time ago for Gallifrey. Back when time travel was first starting there was a scholar called KaRoNo. He documented the exploits of various famous time travel pioneers. During this time, KaRoNo discovered that High Gallifreyan, the language used at the time, was not efficient when talking about time travel. It lead to much confusion, lengthy descriptions, and inaccurate data. When searching for a better way to describe time travel, KaRoNo started to write in circles instead of in a linear fashion. This evolved over time into what we now know as KaRoNo GaLiFeYaXi, named after it's starter.
