Isn't this an argument against using TAI in certain applications though? i.e. if you're designing a system which relies on non-leapsecond-updated devices to be in sync with devices that are capable of being updated, you should always design as such to accommodate the former rather than the latter?
- lmm 8y agoNo? It's an argument for using TAI,because devices that use TAI do not need leap second updates - a clock running TAI that was started in 1970 and never updated will show the same time as a clock running TAI that's started today (or one that was started in 1970 and updated continually), whereas a clock running UTC that wasn't updated will show a different time from one that was updated.
- kazinator 8y agoFor most timekeeping devices, the inherent drift and skew noise floor is above the leap seconds error.
