Complete solution

Shows how to fix tinybird analytics dashboard empty outside Europe unless date adjusted (UTC default). Use it when you hit this exact problem. Skip it when your error message or symptom looks different.

TL;DR

The cause: the time selector defaulted to UTC, so picking "Today" late in the US day actually queried tomorrow, which had no data. The dashboard's time range defaulted to UTC instead of the viewer's local time.

Steps

  1. The Tinybird web analytics dashboard showed no data at all for users outside Europe, except the "users in the last 30 minutes" widget. Loading it in the US gave an empty dashboard. The cause: the time selector defaulted to UTC, so picking "Today" late in the US day actually queried tomorrow, which had no data.
  2. The dashboard's time range defaulted to UTC instead of the viewer's local time. Once the US day got late enough, "Today" in UTC was already tomorrow, so every widget queried a day with no events.
  3. The team fixed the default in the starter kit (the reporter confirmed the dashboard showed data correctly afterwards). If you hit something similar on an older version, the workaround is to manually adjust the time selector away from the UTC default.
