What this does
Every city is bound to an IANA time zone identifier such as Asia/Shanghai or America/New_York. The current time, UTC offset and daylight saving status are all derived from that identifier for the moment in question, rather than from a fixed offset.
Zone rules come from the IANA time zone database shipped with the runtime and follow its updates. No external time service is called.
