Hi,
as far as I know, timeZone was added to fix a bug ([A12-13004]<INTERNAL_LINK>). It is not a full solution for handling time zones.
Additionally, I found in [A12K-1362]<INTERNAL_LINK> the following statement:
For the time beeing we will only use and test the time zones “UTC” and “Europe/Berlin”. We will not take account for half hour time zones or similar things.
Therefore, I would not expect that it is enabled to set another time zone other than “UTC” for migration yet.
“For new Document Models it is set automatically to “UTC”. If a workspace contains document models with differing time zones, the models which use time zone “UTC” will be marked as invalid.”
As a result, you should think carefully about using the “Europe/Berlin” timezone. It could lead to confusion when creating new Document Models, which will be invalid if not modeled correctly.
