About the time in Altamira
Clocks in Altamira 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.
Altamira runs on America/Manaus, 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.
If you are coordinating from another country, the shortcut is the working window: a normal Altamira day of 09:00–17:00 falls between 13:00–21:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
