> Introduced Timespan class>>defaultOffset. This is the offset that will be used for creation of all Timespans when an offset is not specified. When an offset is specified or involved in construction or calculation, the result is now produced in terms of the source offset.
> For example, Date today now produces a globalized date by default. However, "Date starting: (DateAndTime year: 2004 month: 2 day: 29 hour: 13 minute: 33 second: 0 offset: 2 hours)" produces a Date.whose start is expressed in terms of UTC+2.
> The default defaultOffset is Duration zero so that Squeak will have fast, globalized Dates out of the box. Globalized Dates are common for applications.
> Legacy localized Dates can be obtained by evaluating "Date localize" so that, when an offset is not specified or otherwise involved in the input, the local offset will be used.

I like this one because
| dateAndTime |
dateAndTime := DateAndTime year: 2012 month: 1 day: 1 hour: 1 minute:
1 second: 1 offset: 10 hours.
self assert: (dateAndTime asDate includes: dateAndTime)
will succeed whatever your local time zone...
