Time zones look like a solved problem until a government changes one. WorldTimeZone.com has spent more than 28 years dealing with what happens after that sentence.
The site says it now contains more than 37,000 pages and provides local-time information for more than 35,000 locations. Its tools include world clocks, regional time maps, an international call planner, an interactive map, a sun clock, daylight-saving information and a stream of time-zone news.
That sounds excessive until you remember that civil time is political infrastructure.
Rules change. Daylight-saving policies change. Countries move dates. Cities and territories do not always follow the neat boundaries people expect from a classroom map.

WorldTimeZone.com also preserves historical time-zone charts, including older world maps and material about changes to the International Date Line.
That historical layer is valuable because most current time tools answer one question: what time is it there right now?
Researchers sometimes need a different question: what did the official time relationship look like in a particular year?
The site is also a fine example of the old specialist web scaling horizontally. Instead of replacing its original reference idea with a generic blog, it kept adding pages for regions, cities, daylight-saving changes, abbreviations, travel, historical charts and planning tools.
Its about page notes references and links from educational institutions, businesses, media outlets and organizations ranging from NASA to the Library of Congress. The design is busy by modern standards, but the purpose is obvious everywhere: get from a place name to a useful time answer.

WorldTimeZone.com survives because the subject never stops changing. Time zones may be boring right up until the exact minute matters.
