Focal lengths: cm vs. mm vs. in?

Time zones

To those who have (had) a hard time with strange measurement units, here in Europe until few decennia ago (I did not encounter it) national time zones were off those 15° longitudes, which resulted when crossing borders in strange differences in time e.g. 19m 32,13s ...[/QUOTE]

I believe that was prior to WWII, when (e.g.) Amsterdam time (which was the official time for the Netherlands) was preceding Berlin time by around 20 minutes. In all countries that were occupied by Germany during the war, the Wehrmacht quickly changed that to our current time zones, separated by 1 hour. It was left at that after the war by most states in western Europe (I don't know about the countries behind the iron curtain) because it wasn't such a bad idea. (The Netherlands also retained wages taxes and "Kündigungsschutz", both pieces of German occupation legislation, after the war untill this day.)
 
Hoi neighbor,

Yes you are right in all aspects.
(My example referred to the Amsterdam vs. Berlin time).
That reference to those social security issues is really seldom done in the Netherlands...

To move back to photography... I still calculate ASA (or ISO, as ASA did overcome DIN in that transocean couple) values to DIN values...
 

That barely scratches the surface of the Quebec weirdness...

Hey, don't you try to teach this Quebecer something about his country's weirdness!
 
Quebec is a country? I thought it was part of Canada? Either way, it's in America - right?

Depends on who you ask....if the french speaking Quebecoie (sp?) had their way, it'd probably be on a different planet altogether.

Yeah, let's just call it a nation for now.
