This means that two date strings that appear equivalent may result in two different values depending on the format of the string that is being converted.The ECMAScript specification states: If the String does not conform to the standard format the function may fall back to any implementation–specific heuristics or implementation–specific parsing [email protected] Thanks Michael (it looks was copy paste :))[email protected] returned param ret is true or false and that's enough.
var n Year = o Full Year(); var n Month = o Month() 1; // 0 based var n Day = o Date(); // Validation flags.
If the string is date and time in ISO 8601 format, it will be treated as local.
While time zone specifiers are used during date string parsing to interpret the argument, the value returned is always the number of milliseconds between January 1, 1970 UTC and the point in time represented by the argument or objects produced using those strings may represent different moments in time depending on the version of ECMAScript supported unless the system is set with a local time zone of UTC.
Direct call: A number representing the milliseconds elapsed since January 1, 1970, UTC and the date obtained by parsing the given string representation of a date.
If the argument doesn't represent a valid date, (4 hours, 30 minutes east of the Greenwich meridian). The local time zone is used to interpret arguments in RFC2822 Section 3.3 format that do not contain time zone information.
You don't need to do that when using HTML 5 type="date" attribute (the format then will be forced to be YYYY-MM-DD).
