Comment 1 for bug 925361

what about optionally (1) displaying the time zone next to the date/time ?

(1) obviously it depends on the "context" in which the date / time is displayed

* a calendar entry must always be in users time zone
* a invoice date must always be in the time zone where it has been issued - if different from the users time zone the time zone should be displayed / printed to avoid misunderstandings.
