Welcome To The Time Zone
summary
A C++ library built on <chrono> (header tzh with companion date library on GitHub) parses the full IANA tzdb and exposes every rule, lets code iterate all ~300 zones, and narrows an ambiguous abbreviation to six candidates in the demo. It is type-safe, distinguishes civil vs. absolute time, supports custom calendars and sub-second precision, and adds a UTC clock so conversions are leap-second aware. Initial DB load costs milliseconds then operations cost microseconds; database size ≈800KB.
