Maybe the reason it is set up like that is due to the various timeI suspect you're right. Relative time ("ago") is the same no matter what time zone the user is in.
Frances I canít remember if I indicated in my profile on Yahoo GroupsYes, the time zone listed in your Yahoo Account Info page is used to display date/time information throughout Yahoo - except on calendars (they have their own).
It used to be that you had to set the Account Info time zone correctly, but the last time I looked it is setting your time zone automatically based on location information.
I know any message I receive from the various Yahoo Groups, they show myThat's being done by Outlook. The Date field of email headers specify both a Date/Time and the UTC* offset of that Date/Time. With that information Outlook can convert the Date/Time to anyone's local time. For example, your first message in this thread had:
Date: Wed, 21 Jan 2015 19:23:32 -0500The "-0500" is the offset from UTC of that date/time. I live in in UTC-0800, so my email software subtracts the difference in those offsets (3 hours) from that date/time and displays your messages as having been sent at "04:23 PM 1/21/2015" - in my local time.
