Commit odoo/enterprise@4bbf70f was fixing a timezone issue. Datetimes coming
from lists inserted in a spreadsheet were always displayed in UTC.
However, this commit also changed the formatting behavior.
Before the fix: date/datetimes were dispalyed with the server format
After: they are displayed with the local format (FR if the user lang
is French)
This can lead to issues because spreadsheet only understands a
handfull of date(time) format.
For example, it doesn't understand dd/mm/yyyy format but only
the other way around (mm/dd/yyyy)
This commit restores the previous format (server format), while
preserving the timezone conversion.
