About the Asia/Tehran timezone
Asia/Tehran is an IANA time zone identifier — the canonical, globally unique name for the civil time observed in Tehran, Iran. Every operating system, programming language, and calendar product that supports time zones recognises this string and uses it to compute the correct local time for any given moment.
IANA time zones are maintained by the Internet Assigned Numbers Authority (IANA) and track the historical, current, and planned future civil time of every region — including daylight saving time (DST) transitions, country-level changes, and historical anomalies. This is why software like macOS, Linux, Windows, and major cloud services all use the same identifiers.
