@erincandescent @snowfox indeed CLOCK_TAI works by setting CLOCK_REALTIME plus the (integer) kernel TAI offset…
…but I'm a strong believer in incremental steps and I'd really like to see more software use CLOCK_TAI (as appropriate), and tackle representation of leap-smearing separately (because these things don't block each other)
The thing more concerning to me is filesystem support for TAI timestamps 😩
