Per-user time zone settings

When I'm looking at recently built projects in Bamboo, it will say something like "4 minutes ago" or "2 days ago". If I mouse over those strings, it pops up a tooltip that shows the approximate time of the build (e.g. "Fri, 13 May, 07:48 PM"). There are several problems with this:

0) "X minutes ago" is only useful if I know when the page was loaded. Nothing on the page indicates the loading time, so if I look at such a page several minutes (or hours) after it was loaded, I have no idea how long ago "X minutes ago" was. Maybe a Javascript timer to update the times in the page every so often so that it remains accurate when the page is open for long periods? It's not at all uncommon to have numerous tabs open and come back to them later.

1) I'm in PDT (-0700) and the time displayed is UTC (+0000). Other people using the same Bamboo instance are scattered around the world; I want times displayed to me in my time zone, and they want theirs. Forcing us all to agree on a single time zone display (when we have individual logins!) is suboptimal. I should be able to set a time zone in my user profile.

2) The format of the displayed timestamp (D, d M, h:i) is not remotely what I want. I want to be able to set a UNIX `date (1)`-style time string so that it shows time stamps the way I want them. (At the very least, give us a few preconfigured options, like ISO 8601, US, UK, whatever.)

3) Software intended for use by people distributed over a wide area should always, ALWAYS display a time zone with a timestamp. The example above ("Fri, 13 May, 07:48 PM") is increasingly meaningless the longer the page has been open. In order to get an accurate timestamp, I have to reload the page. This is obviously less of an issue if the above issues are addressed, but still: there is no good reason to ever fail to display a time zone in an environment like this.
