Argentina's clock has moved many times. The country used summer time on and off for decades, the last time from October 2008 to March 2009, and some provinces briefly kept a different hour from the capital. Since 2009 the whole country has been on UTC−3 all year.
The IANA time zone database keeps separate entries for several Argentine provinces because of that history, all of which now show the same time as Buenos Aires.
Why evenings in Buenos Aires run late
By longitude, Buenos Aires belongs closer to UTC−4. Running on UTC−3 means late sunrises in winter, around 8:00 AM in June, and long evenings. It also fits the city's famously late hours: dinner at 9:00 or 10:00 PM is normal.
Is Argentina on the same time as Chile?
Only part of the year. Mainland Chile uses UTC−4 in winter and UTC−3 in summer, so Santiago matches Buenos Aires from September to April and is one hour behind from April to September.
How does Buenos Aires line up with Europe?
Madrid is four hours ahead in the European winter and five in summer; London three and four.

Hours to add to the time in Buenos Aires; a minus sign means the other city is behind
Argentina's fixed offset means the gaps move only with other countries' clocks. New York is two hours behind in the northern winter and one in summer. For a full Eastern Time grid, use the ART to EST converter; the São Paulo clock shows Brazil, on the same hour.
Several provinces, such as San Luis, have tried keeping a different hour from Buenos Aires in the past; none does today.
