History
How Aruba keeps time.
Aruba has maintained Atlantic Standard Time (UTC-4) since establishing a consistent relationship between the island's solar noon and civil time that suited its latitude. The island did at one time observe daylight saving time and went as far as experimenting with UTC-4:30 — an unusual half-hour offset bridging the gap between Atlantic and Eastern time zones. This intermediate offset was short-lived. Aruba eventually settled on the straightforward UTC-4 that avoids the clock-switching complications of DST, reducing scheduling issues for both locals and the large tourism industry. The simplification matched the needs of an island that doesn't gain much evening daylight benefit from DST given its tropical location.
