Can I support too. The web site dates is as impenetrable to non-Americans as Degrees Celsius were to the US Citizens I met on a recent tour of the Canadian Rockies¡
I run yahoogroups with large proportions of members in the USA, Canada, UK, rest of Europe, Australia and some other countries.? In order for dates to be readily and instantly understandable, the members need to be able to know, without thinking,unambiguously, that a message posted on 1/8/18 was posted on 1st August 2018, or 8th January 2018 and the only way of doing this instantly is to enable them to see dates in their local date format.
The same goes for time format: I far prefer to use the 24 hour clock (I'm from the UK where 12 hour and 24 hour clocks are in common usage), but many of my US members find that quite difficult.
This issue is slowing down a transfer of some of my groups from yahoogroups to io groups: enforcing a single format, whether the US format or ISO format (which has the benefit of annoying almost everyone equally), or the DD/MM/YYYY format used by most of the world, smacks of cultural imperialism of one form or another!??
