The seconds/nanoseconds are always positive when normalized.

Are you sure? I have just changed (for testing) to this:

DateAndTime localTimeZone: (TimeZone timeZones detect: [:tz | tz abbreviation = 'EST']).

And now if I do:

DateAndTime now offset asSeconds ----> -18000

The seconds/nanoseconds in DateAndTime itself are like that, the TZ offset can be positive and negative: http://en.wikipedia.org/wiki/Timezone <<Most of the 40 time zones on land are offset from Coordinated Universal Time (UTC) by a whole number of hours (UTC−12 to UTC+14), but a few are offset by 30 or 45 minutes.>>
