You can change the display date format in Settings->Preferences->User Interface. 

There's a Date Format and Pretty Dates option (needs to be off I think to keep all dates even close ones same format). 

Don't know about the sort order. You can change it by clicking on the settings icon on the left of the title header but as far as I know its global not per folder.

People,

Generally I have the most recent mails sorted to the top of the display - today I noticed that some mails that came in today and yesterday were down the bottom of the list instead of at the top - AFTER I had moved them from the INBOX to their appropriate category folder.  There seems to be no controls on folders that would affect this so I am not sure what is going on.  The only clue I have is that the displayed dates for these problem mails are of the form: "Today|Tue HH:MM" instead of the usual International Format of: "YYYY-mm-dd HH:MM" so I am assuming it is something weird because of that - I imagine in a week's time they will be displaying in the correct order at the top of the list.

This problem brings me to another another whinge (I think I have asked about this before) - I would like ALL my dates to be in the International Format instead of having identifiers "Today|Mon-Sun HH:MM" - is it possible I can configure this somehow?

Thanks,

Phil.
