Hi Mark,
As Duane mentioned this topic has been raised as -
HERE. Pity it's taking so long to change what I would think is a simple enhancement (but I'm no programmer (;>)
It is a bit infuriating in my subject lines I have to preface with a European date to make sure the members of my Groups (amateur radio - and times - 24hr clock in Z/UTC/GMT) can recognise the date format correctly
01/06/18 - 1st of June or 6th January? Of course the 1st of June from our perspective.
And a last, a lot of progressive on-line sites are starting to adopt the standard for dating format YY/MM/DD/M and no AM/PM just 24hrs.
Cheers
Jack(;>J
