It's far more complicated than that. There are 24 geographic time zones but zoneinfo has to deal with local civil time as regulated, often rather capriciously, by national, regional, and local governments. Examples: Do you know how many versions of DST/Summer Time there are? Did you know that some jurisdictions set their clocks 1/2 hour away from what their geographic time zone indicates? That many jurisdictions ignore their geographic time zone and use a politically convenient one? That some countries have "moved" across the international date line? -- John Hasler jhas...@newsguy.com Elmwood, WI USA
