This post brings back horrors when I was trying to figure out from the logs why there was a sudden doubling of requests and orders on 2016-12-31:23:59:59. This is the time I learned that Linux does not distinguish the leap second from the second before it. This led me down to a rabbit hole of reading up on what the representation of a leap second was and found that there was none for Linux timestamp. Fortunately, this was in December 2019. I can only imagine the pain SREs had to suffer from on 2017's New Year's day on top of Cloudflare going down.
