Google calendar showing events in utc

I recently moved from hassbian (on pi3b) to hassio (vm on esxi) and all of a sudden I have an issue with my calendars from google. (same version of HA btw)

{{now()}}
{{utcnow()}}
{{state_attr("calendar.alarm", "start_time")}}
{{as_timestamp(state_attr("calendar.alarm", "start_time"))|timestamp_local}}

gives this output"

2019-12-31 13:42:58.759997+01:00
2019-12-31 12:42:58.760028+00:00
2020-01-06 06:20:00
2020-01-06 07:20:00

so whereas on the old setup the time from the calendar were in local time, now they are in utc? the calendar is set to the correct timezone as well anyone any idea? or should I file a bug report?
