// |reftest| skip-if(winWidget&&!xulRuntime.shell) -- Windows browser in automation doesn't pick up new time zones correctly
// Repeats the test from "time-zones.js", but uses POSIX instead of IANA names
// for the time zones. This allows to run these tests on Windows, too.
//
// Windows only supports a very limited set of IANA time zone names for the TZ
// environment variable.
//
// TZ format supported by Windows: "TZ=tzn[+|-]hh[:mm[:ss]][dzn]".
//
// Complete list of all IANA time zone ids matching that format.
//
// From tzdata's "northamerica" file:
// EST5EDT
// CST6CDT
// MST7MDT
// PST8PDT
//
// From tzdata's "backward" file:
// GMT+0
// GMT-0
// GMT0
//
// Also supported on Windows even though they don't match the format listed
// above.
//
// From tzdata's "backward" file:
// UCT
// UTC
//
// From tzdata's "etcetera" file:
// GMT
// Perform the following replacements:
// America/New_York -> EST5EDT
// America/Chicago -> CST6CDT
// America/Denver -> MST7MDT
// America/Los_Angeles -> PST8PDT
//
// And remove any tests not matching one of the four time zones from above.
