About the time in Buenos Aires
The zone identifier America/Costa_Rica is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Costa_Rica keeps pointing at Costa Rica time whatever the date, which is why every timestamp on this page is built from it.
Buenos Aires sits at latitude 9.10, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 12h 21m is one point on that curve, not a fixed value.
Clocks in Buenos Aires stay put all year. There is no summer-time switch to remember, so UTC −6 is what you will get in January and in July alike — useful if you book recurring calls with people in Costa Rica.
