Issue Summary

When exporting calendars from Team Calendars set to the America/Sao_Paulo timezone, the exported data incorrectly assumes that daylight saving time is still in effect. Brazil no longer has DST since 2019. As a result, when importing the calendar into another application within the same timezone, all events are shifted one hour ahead.

Steps to Reproduce

1. Create a calendar event in Team Calendars with the timezone set to America/Sao_Paulo.
2. Export the calendar.
3. Import the exported calendar into another application that supports the America/Sao_Paulo timezone.
4. Observe the time of the events in the imported calendar.

Expected Results

The event times should remain consistent and correctly reflect the local time in the America/Sao_Paulo timezone without any DST adjustments.

Actual Results

The events are shifted one hour ahead, indicating that the application incorrectly applies DST to the America/Sao_Paulo timezone.

Workaround

Manually update the .ics by replacing every -0200 with -0300.
