While 15.9.1.1 explicitly says leap seconds are ignored by ECMAscript, the ISO 8601 timestamp format allows them.
15.9.1.15 (used by Date.parse) does dictate ranges for months and dates (days of month), but they don't specify the range for hours, minutes and (milli)seconds (although a note says 00 is the same as 24, fine). On the other hand, "the number of x passed since y" can be interpreted as a range. But does this interpretation come through the viewport of ECMAscript (ignoring leap seconds) or the real world. The last paragraph in 15.9.1.15 before the notes says to reject all dates it cannot parse. Now my question is, should "T23:59:60" be a valid timestamp as parsed by Date.parse? Which basically comes down to the question whether Date.parse should only parse dates Ecmascript can produce itself or dates ISO 8601 could produce. If up in the air, my vote goes to allow leap second notation. The current Firefox implementation (for example) seems to reject it. - peter _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
