- * This is a bit tricky to implement portably. The result depends

- * If e.g. UNIX APIs are used, they'll have portability issues with
- * very small and very large years.
- *
- * Current approach:
- *
- * - Stay within portable UNIX limits by using equivalent year mapping.
- * Avoid year 1970 and 2038 as some conversions start to fail, at
- * least on some platforms. Avoiding 1970 means that there are
- * currently DST discrepancies for 1970.
- *
- * - Create a UTC and local time breakdowns from 't'. Then create
- * a time_t using gmtime() and localtime() and compute the time
- * difference between the two.
- *
- * Equivalent year mapping (E5 Section 15.9.1.8):
- *
- * If the host environment provides functionality for determining
- * daylight saving time, the implementation of ECMAScript is free
- * to map the year in question to an equivalent year (same
- * leap-year-ness and same starting week day for the year) for which
- * the host environment provides daylight saving time information.
- * The only restriction is that all equivalent years should produce
- * the same result.
- *
- * This approach is quite reasonable but not entirely correct, e.g.
- * the specification also states (E5 Section 15.9.1.8):
- *
- * The implementation of ECMAScript should not try to determine
- * whether the exact time was subject to daylight saving time, but
- * just whether daylight saving time would have been in effect if
- * the _current daylight saving time algorithm_ had been used at the
- * time. This avoids complications such as taking into account the
- * years that the locale observed daylight saving time year round.
- *
- * Since we rely on the platform APIs for conversions between local
- * time and UTC, we can't guarantee the above. Rather, if the platform
- * has historical DST rules they will be applied. This seems to be the
- * general preferred direction in Ecmascript standardization (or at least
- * implementations) anyway, and even the equivalent year mapping should
- * be disabled if the platform is known to handle DST properly for the
- * full Ecmascript range.
- *
- * The following has useful discussion and links:
