Timestamp issues

[mweiner1]

1. The "edited" field on individual question view vs. the "all questions" view doesn't match - they seem to be using different time zones (one is exactly five hours behind the other).

2. Clicking on column headers such as "edited" or "modified" in the "all questions" view does something, but it is not clear what. By analogy to most other interfaces, this ought to sort the column from smallest to largest or vice versa if clicked once, and reverse the sort if clicked twice. Clicking rearranges the questions in some fashion, but looking at the timestamps shows that it's not ordered by that field.
