About the time in Altair
If you are coordinating from another country, the shortcut is the working window: a normal Altair day of 09:00–17:00 falls between 12:00–20:00 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.
Altair runs on America/Sao_Paulo, which puts the city UTC −3 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.
The zone identifier America/Sao_Paulo is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Sao_Paulo keeps pointing at Sao Paulo time whatever the date, which is why every timestamp on this page is built from it.
