WDYM? Leap seconds are a 61st second, hitting 60 before 00 next minute. https://nrc.canada.ca/en/certifications-evaluations-standard...

This makes sense for timestamps in traditional logs. You don't have to second guess the order of things, especially across multiple systems or services.

I meant unix and NTP times, which are supposedly just monotonic numbers marching forward (except for leap seconds), not the UTC representation over abstract time.

I know we just get a 60th second in a minute. What unix and NTP timestamps do (or originally did) was repeating a second. Then we got other hacks to keep monotonicity, like smearing. Not without tradeoffs.

Thanks for explaining! It's indeed crazy that "this is still a thing".
