I found out that one app has different timezone settings in the configuration file than another.
"timezone": "CET", "timezoneOffset": 60,
"timezone": "CEST", "timezoneOffset": 120,
As one is CentralEuropeanTime and the other CentralEuropeanSummerTime (which changes twice a year) - is Adobe also switching between Summer- and Wintertime, so that the App e.g. Launches are tracked on a correct timestamp?
