About the time in Rio Branco
Rio Branco runs on America/Cuiaba, which puts the city UTC −4 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Clocks in Rio Branco stay put all year. There is no summer-time switch to remember, so UTC −4 is what you will get in January and in July alike — useful if you book recurring calls with people in Brazil.
Rio Branco sits at latitude -15.24, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 11h 40m is one point on that curve, not a fixed value.
