How to get DateTime with Timezone Offset (8601 format) in Javascript
※ Download: Javascript iso 8601
Polyfill This method was standardized in ECMA-262 5th edition. Engines which have not been updated to support this method can work around the absence of this method using the following shim: if! Note that getTimezoneOffset returns an offset which is positive if the local timezone is behind UTC and negative if it is ahead. Because parse is a static method of , it is called as Date.
A related tip is that you can perform multiple assignments within the initialization, test and increment terms of a for statement, merely by delimiting them with commas. How do I render the title portion of the following snippet?

It is not recommended to use Date. There are still many differences in how different hosts parse date strings, therefore date strings should be manually parsed a library can help if many different formats are to be accommodated.

Syntax Direct call: Date. Return value A number representing the milliseconds elapsed since January 1, 1970, 00:00:00 UTC and the date obtained by parsing the given string representation of a date. If the argument doesn't represent a valid date, is returned. This function is useful for setting date values based on string values, for example in conjunction with the method and the object. Given a string representing a time, parse returns the time value. GMT and UTC are considered equivalent. The local time zone is used to interpret arguments in format that do not contain time zone information. ECMAScript 5 ISO-8601 format support The date time string may be in a simplified format. Where the string is ISO 8601 date only, the UTC time zone is used to interpret arguments. If the string is date and time in 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 00:00:00 UTC and the point in time represented by the argument or NaN. Because parse is a static method of , it is called as Date. Therefore 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. 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. Fall-back to implementation-specific date formats 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 algorithm. Unrecognizable strings or dates containing illegal element values in ISO formatted strings shall cause Date. However, invalid values in date strings not recognized as simplified ISO format as defined by ECMA-262 may or may not result in , depending on the browser and values provided, e. See also this on how the parsing works. Other examples: new Date 'foo-bar 2014'. Specifications Specification Status Comment Standard Initial definition. Implemented in JavaScript 1.
