Hello, the proof of work sets a certain pace in the TIMECHAIN and this timechain therefore has a smallest time unit of 1 single block. But there are multiple time schedules present in the timechain. most notably the halving schedule that recently happened. And also the difficulty adjustment. Do you know of any other time schedule that is coded in the timechain? Because that itself can be refferred to as a timeunit on the timechain. Like we have days and months, we got blocks and halvings and etc.
