Local time rules vary from place to place. Compare the current time range, UTC offsets and linked places without treating the continent as one time zone.
South America: Current time
Syncing • Using device timeNote: the value above does not include device-clock drift accumulated after calibration. This is generally no more than ±1 ms per minute, but the actual rate varies by device.The lowest round-trip latency measured between your browser and the current time-service node. It is typically affected by physical distance, network routing, access quality, and current congestion.Network latency describes the measured connection. It is separate from the estimated time-error range and must not be treated as that range or divided in half.This error does not show whether your device clock is fast or slow.
This metric calculates the UTC offset for every IANA time-zone identifier listed on this page at the same instant, then measures the difference between the smallest and largest offsets; the result may change when time-zone rules change.
