// Date => 'date object or valid date string'
// Option => 'timestamp option [timestamp in sec,timestamp in millisecond]
// Default option is millisecond

dateUtil.toTimestamp(new Date()); //Show timestamp in milliseconds [Default]
dateUtil.toTimestamp(new Date(),'ms'); //Show timestamp in milliseconds
dateUtil.toTimestamp(new Date(),'sec'); //Show timestamp in sec

Basic Example :

var dateUtil = require('date-format-utils');
var date = new Date('1/18/2017, 1:30:00 PM');
console.log(dateUtil.formatDate(date,dateUtil.ISO8601_FORMAT,330));
console.log(dateUtil.formatDate(date,dateUtil.ISO8601_WITH_TZ_OFFSET_FORMAT,330));
console.log(dateUtil.formatDate(date,dateUtil.DATETIME_FORMAT,330));
console.log(dateUtil.formatDate(date,dateUtil.DATE_FORMAT,330));
console.log(dateUtil.formatDate(date,dateUtil.TIME_FORMAT,330));

console.log(dateUtil.toTimestamp(date));
console.log(dateUtil.toTimestamp(date,'ms'));
console.log(dateUtil.toTimestamp(date,'sec'));
console.log(dateUtil.toTimestamp(date,'xyz'));

// The example displays the following output:
//      2017-01-18 13:30:00.000
//      2017-01-18T13:30:00.000 +0530
//      2017-01-18 01:30:00.000 PM
//      2017-01-18
//      01:30:00 PM

//      1484726400000
//      1484726400000
//      1484726400
