Can one UTC offset identify my location?

No. Many regions share an offset, and browser settings can change the exposed readings.

Are half-hour or quarter-hour offsets suspicious?

No. They are normal timezone configurations and are handled without rounding.

Does an offset mismatch prove a VPN leak?

No. This local check does not query your IP address, VPN endpoint or physical location.
