2026-09-30 — Behavior change
Criteo data sources can now report in a chosen timezone. When a Criteo data source is created, an optional Timezone can be selected next to Currency. The timezone sets where each reporting day starts and ends, so daily figures can differ from Criteo’s own reporting when it uses a different timezone. If no timezone is selected, the data source uses UTC, and existing Criteo data sources stay on UTC. The timezone cannot be changed from the data source settings after creation; to change it, emailsupport@adriel.com, and Adriel switches the timezone and re-collects the data source’s data. See FAQs for details.
