Calendar events display in wrong timezone (Pacific/Apia instead of system timezone)

[ondohotola]

Description

When listing calendar events, gog calendar events displays times in Pacific/Asia (UTC+13) instead of the user's local timezone or the event's
configured timezone.

Steps to Reproduce

1. Create a calendar event with Africa/Windhoek timezone (UTC+2):

   gog calendar create primary \
     --summary "Dr XXXXX Followup" \
     --from "2026-04-08T09:00:00+02:00" \
     --to "2026-04-08T09:20:00+02:00" \
     --location "Windhoek, Namibia"

2. List events:
  ```bash
    gog calendar events --account <email> --from 2026-04-08 --to 2026-04-09

Expected Behavior

Event should display as:

  09:00–09:20  Dr XXXXX Followup

Actual Behavior

Event displays as:

  20:00–20:20+13:00  Dr XXXXX Followup

Note: 09:00+02:00 and 20:00+13:00 represent the same instant, but the display timezone is incorrect.

Environment

• gog version: v0.12.0 (c18c58c 2026-03-09T05:53:14Z)
• OS: macOS Darwin 25.4.0 (arm64)
• System timezone: Africa/Windhoek (UTC+2)
• gog calendar time output:

    timezone       Africa/Windhoek
    current_time   2026-04-07T22:22:21+02:00
  

Additional Context

• Event JSON from API shows correct timezone: "timeZone": "Etc/GMT-2"
• Google Calendar web UI displays correct local time (09:00)
• Only gog calendar events plain text output is wrong
• JSON output (-j) may also be affected

The issue appears to be in how gog converts and displays event times, not in how events are stored.

Workaround

Edit events directly in Google Calendar web UI, which displays times correctly, but this is counterproductive.
