### TIL about UTC leap seconds and now nothing is real.
* atomic time is so accurate, it exposes an inaccuracy in keeping time by the rotation of the earth
* UTC needs to be "slowed down" with leap seconds to account for the discrepancy
* We can't know when a leap second occurs beyond the next six months
* there have been 26 leap seconds in the past 53 years
I was not aware of that! Also, am I the only one who never got the memo to use UTC instead of GMT ?
The topic of "time" is a deep rabbit hole 😂
since 2020 for the first time since recording with this precision the earth day has fallen below 24 hours btw
something is causing the earth to spin a tiny bit faster... like 20ms/year, but still
Yeah, what a fun to implement something that relies on time. Stupid earthquake can shift the earth and we have to adjust the time for it...
People names are similarly surprisingly tricky problem fwiw.
Read about time smearing as a way to mitigate leap seconds, fun stuff 😆
And as a dev whenever you have to handle timezone stuff you use an existing library and say praises to the greybeards who figured all this shit out!
