Having spent a large amount of time dealing with interfacing a Julian/(British) Gregorian calendar system to ES (complete with missing days in 1752) and other large codebases to ES which have to consume the datetimes, proleptic Gregorian is surely the only sane choice. Calendars are like time zones -- they just change so infrequently that most people don't consider them as such. But it doesn't make sense to try to use the interpretation of calendar(s) in any one country as the reference any more than it does to use EST/EDT as the basis for times instead of UTC. Like it or not, proleptic Gregorian is the closest we have to a "universal" calendar for computers. Even if calendar transitions were not dependent on vantage point, supporting the Julian/Gregorian hybrid slows date code by adding conditionals as opposed to being a simple formula. >>> and Explorer formats it as being in the year 1 BC.

Can anyone comment on why Safari chose that implementation? -Andrew _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
