Hannes Hirzel asked (in the DateAndTime thread) what my Timestamp class does and if it works with 3.2. Well, it files into my 3.2 alpha image just fine (updated to 4664). I'm sorry I don't have a 3.2 gamma image handy. The class is fairly straightforward, Hannes, if you want to take a quick look at it.
As was noted in the preamble, this class does not implement time zones, but I think it is useful even without them. If time zones are also needed, I suppose someone could look at the work that was done by Lex Spoon and others. In any case, my class is very lightweight (no refactoring of the base classes is necessary to use Timestamp in your image).
I implemented Timestamp when I needed to port some of my code from VSE to Squeak. At the time, I banged on this code pretty hard, so I expect that it should work as you would expect.
I'm sorry I haven't had time to write SUnit tests for this. But before sending this note to the list, I inspected each of the following statements (see below), exercising a good chunk of the protocol -- everything seemed fine.
I hope you find this class as useful as I do. I imagine that it could be used quite handily in such applications as Celeste, the PDAMorph, etc. Squeak really deserves to have a Timestamp class; lugging dates and times around in arrays is too painful.

PS> For history buffs & people who are already using my Timestamp class: in the original changeset (posted to the list in October of 2000), I had named the class TimeStamp. Since that time, I've discovered that timestamp is a word in its own right, so I changed the name of my class to Timestamp.

Here are some protocol tests:
