===========

[![NPM](https://nodei.co/npm/date-format.png?downloads=true&downloadRank=true&stars=true)](https://nodei.co/npm/date-format/)

node.js formatting of Date objects as strings. Probably exactly the same as some other library out there.

```sh
npm install date-format
```

usage
=====

Formatting dates as strings
----

```javascript
var format = require('date-format');
format.asString(); // defaults to ISO8601 format and current date
format.asString(new Date()); // defaults to ISO8601 format
format.asString('hh:mm:ss.SSS', new Date()); // just the time
format.asString(format.ISO8601_WITH_TZ_OFFSET_FORMAT, new Date()); // in ISO8601 with timezone
```

or

```javascript
var format = require('date-format');
format(); // defaults to ISO8601 format and current date
format(new Date()); // defaults to ISO8601 format
format('hh:mm:ss.SSS', new Date()); // just the time
format(format.ISO8601_WITH_TZ_OFFSET_FORMAT, new Date()); // in ISO8601 with timezone
```

**output:**
```javascript
2017-03-14T14:10:20.391
2017-03-14T14:10:20.391
14:10:20.391
2017-03-14T14:10:20.391+11:00
```

Format string can be anything, but the following letters will be replaced (and leading zeroes added if necessary):
* dd - `date.getDate()`
* MM - `date.getMonth() + 1`
* yy - `date.getFullYear().toString().substring(2, 4)`
* yyyy - `date.getFullYear()`
* hh - `date.getHours()`
* mm - `date.getMinutes()`
* ss - `date.getSeconds()`
* SSS - `date.getMilliseconds()`
* O - timezone offset in ±hh:mm format (note that time will still be local if displaying offset)

Built-in formats:
* `format.ISO8601_FORMAT` - `2017-03-14T14:10:20.391` (local time used)
* `format.ISO8601_WITH_TZ_OFFSET_FORMAT` - `2017-03-14T14:10:20.391+11:00` (local + TZ used)
* `format.DATETIME_FORMAT` - `14 03 2017 14:10:20.391` (local time used)
* `format.ABSOLUTETIME_FORMAT` - `14:10:20.391` (local time used)

Parsing strings as dates
----
The date format library has limited ability to parse strings into dates. It can convert strings created using date format patterns (as above), but if you're looking for anything more sophisticated than that you should probably look for a better library ([momentjs](https://momentjs.com) does pretty much everything).

```javascript
var format = require('date-format');
// pass in the format of the string as first argument
format.parse(format.ISO8601_FORMAT, '2017-03-14T14:10:20.391');
format.parse(format.ISO8601_WITH_TZ_OFFSET_FORMAT, '2017-03-14T14:10:20.391+1100');
format.parse(format.ISO8601_WITH_TZ_OFFSET_FORMAT, '2017-03-14T14:10:20.391+11:00');
format.parse(format.ISO8601_WITH_TZ_OFFSET_FORMAT, '2017-03-14T03:10:20.391Z');
// returns Date
```


code:
"use strict";

function padWithZeros(vNumber, width) {
  var numAsString = vNumber.toString();
  while (numAsString.length < width) {
    numAsString = "0" + numAsString;
  }
  return numAsString;
}

function addZero(vNumber) {
  return padWithZeros(vNumber, 2);
}

/**
 * Formats the TimeOffset
 * Thanks to http://www.svendtofte.com/code/date_format/
 * @private
 */
function offset(timezoneOffset) {
  var os = Math.abs(timezoneOffset);
  var h = String(Math.floor(os / 60));
  var m = String(os % 60);
  h = ("0" + h).slice(-2);
  m = ("0" + m).slice(-2);
  return timezoneOffset === 0 ? "Z" : (timezoneOffset < 0 ? "+" : "-") + h + ":" + m;
}

function asString(format, date) {
  if (typeof format !== "string") {
    date = format;
    format = module.exports.ISO8601_FORMAT;
  }
  if (!date) {
    date = module.exports.now();
  }

  // Issue # 14 - Per ISO8601 standard, the time string should be local time
  // with timezone info.
  // See https://en.wikipedia.org/wiki/ISO_8601 section "Time offsets from UTC"

  var vDay = addZero(date.getDate());
  var vMonth = addZero(date.getMonth() + 1);
  var vYearLong = addZero(date.getFullYear());
  var vYearShort = addZero(vYearLong.substring(2, 4));
  var vYear = format.indexOf("yyyy") > -1 ? vYearLong : vYearShort;
  var vHour = addZero(date.getHours());
  var vMinute = addZero(date.getMinutes());
  var vSecond = addZero(date.getSeconds());
  var vMillisecond = padWithZeros(date.getMilliseconds(), 3);
  var vTimeZone = offset(date.getTimezoneOffset());
  var formatted = format

  return formatted;
