When opening a message in KMail, there is a gray
rectangle area above
the message containing the basic To/From/Subject
information.
In Trinity there is a blue box at the right side of
the gray area. The
blue box uses a gradient background and contains the
current time of the
person who sent the message.
There is a related configuration option in Appearance,
Message Window,
named "Show current sender time."
How is the current sender's time being determined? Is
this a local
calculation or is KMail fetching data from somewhere
online before
calculating and displaying the time?
I suspect the date/time you are seeing is actually the time the mail was sent by the originator rather than his/her current time.
Take a look at the headers for these mails and see how the content of the box compares with the 'Date:' header.
The time is the sender's current time.
I want to know how this information is derived.
