Time is a fundamental to modern life. Yet, closest we have come to a definition for it is: “Time is what clock measures”. This talk is about an overview of different ways time is involved in our life. And how to think about (build a mental model around) TIA, unix timestamp, timezones and more. Some of the things we will cover: Measuring time (ticks, counter and start). Different timelines (TIA, UTC, epoch, timezones). Synchronizing time, across earth. Certain aspects of time in programming, relativity, astronomy and more. We will skip details (partly because I haven’t done the work, partly because each topic might be a field on its own), but the overall picture is still fascinating.
