+In all Persistence Technologies we are storing Timestampes in UTC (with out timezone information)

+==== The Problem
+
+Handling Times correctly is a common Problem
+
+
+==== Our way to handle this
+* UTC in all Persistence Technologie
+* Storage without Timezone
+* Expose Timestamp in Formats with given (UTC)-Timezone
+
+=== Inverting the test-pyramid
+
+* Relying more on End2End-Test (what means more like System Tests)
+* Unit and Integration Test only for that parts with lots of branches in the code

+==== Dev Environment and Profile

+This own is active when the developer runs his application locally
