@Anonymous, please file a feature request for merging date ranges.
@Jörg, not yet possible... but would that be good?

i agree. very nice talk. thanks, derick.

one question: is it possible to add virtually your own timezone? for example: my son is definetely living in a different timezone in the same flat :D I could then use the sublocation parameter: Europe/Berlin/Son.

What about merging date ranges?

Interesting topic, showing how many problems can result from regular operations over time. You can learn how to store the DB information from different time zones.

Very good thought out talk, on a complex subject.

Great samples. Good approach to the subject. I would like to see more examples of date arithmetic using new DateTime object (becouse this object is not commonly known) even without timezone mess - for example newyear or dst change.

Good talk. Many good examples.
