About the time in Arecibo
Arecibo runs on America/Puerto_Rico, 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.
Clocks in Arecibo 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 Puerto Rico.
The zone identifier America/Puerto_Rico is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Puerto_Rico keeps pointing at Puerto Rico time whatever the date, which is why every timestamp on this page is built from it.
