On July 1st 2024 I’ve received my APO-SUMMICRON-SL 50 ASPH, on the white protective box in addition to other information is a date 2024/06/11 (back to front to my European mind) that is the date of manufacture if I am correct. If it that so I received the lens from production line in my hands in 21 days. Nice one Leica.

yyyy/mm/dd is the ISO standard. 

ISO is for the rest of the world. In the US we "prefer the metric system" and use mm/dd/yyyy and other "traditional systems of weights and measures", like inch, feet, slug, thou, ounce, chain, rod, furlong, stuff like that 🥵

Very confused!@!

US is ISO and maybe one day will fit with the rest of the world and use the metric system.

Yes, the confusion over standards has even crashed a Mars probe.  The EU engineers were using SI units, while their NASA colleagues were using Imperial.

https://science.nasa.gov/mission/mars-climate-orbiter/

"Designed to study Mars from orbit and serve as a communications relay for the Mars Polar Lander and Deep Space probes, the Mars Climate Orbiter was unsuccessful due to a navigation error caused by a failure to translate English units to metric. Last contact with the spacecraft was on September 23, 1999, nine months after launch, and an investigation found that the spacecraft burned up in Mars' atmosphere."
