Why Does an Analytics Dashboard Show Different Results After a Time Zone Change?

Changing a reporting time zone can move events across day, week, and month boundaries. Totals may differ even though the underlying events are unchanged, particularly when source systems store UTC and reports use local time.

What to check

Compare the dashboard time zone, user profile setting, source timestamp, daylight-saving rules, and date filter boundaries. Test a few events close to midnight in both systems and check whether the report groups by event time or ingestion time.

Recommended next step

Document the reporting time zone and apply it consistently to related measures. Explain expected shifts in historical views and add a validation check for period boundaries after future configuration changes.
