About the time in Castelar
Castelar sits at latitude -34.65, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 11h 00m is one point on that curve, not a fixed value.
Castelar runs on America/Argentina/Buenos_Aires, 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.
If you are coordinating from another country, the shortcut is the working window: a normal Castelar 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.
