TimeSpan.js

is a library for Node.js or the browser that allows you to easily manipulate and format lengths of time.

Installation

Node.js

npm install TimeSpan.js

var TimeSpan = require("TimeSpan.js")

AMD module support

TimeSpan.js supports loading as an AMD module, it detects AMD like: if (typeof define !== 'undefined' && define.amd)

require(["TimeSpan"],
function (TimeSpan) {
	
})

If AMD is not supported TimeSpan.js will be located at window.TimeSpan

<script src="TimeSpan.js"></script>

window.TimeSpan

Documentation

TimeSpan

The TimeSpan constructor, the new operator is optional.

TimeSpan()

Creates a new TimeSpan with a time of 0.

TimeSpan(milliseconds, [seconds, [minutes, [hours, [days]]]])

Creates a TimeSpan with given amount of time

TimeSpan(Date, Date)

Creates a TimeSpan with the difference between times (the future time should go first for a positive number).

TimeSpan.prototype.add

add(unit, value)

Add value amount of unit to the TimeSpan

Units can be one of:

• milliseconds
• seconds
• minutes
• hours
• days

add(unit)

Add 1 of unit to the TimeSpan

Unit can be

• millisecond
• second
• minute
• hour
• day

TimeSpan.prototype.subtract

Exactly the same as add except values are subtracted instead of added.

TimeSpan.prototype.total

total(unit)

Returns the total number of unit in the TimeSpan.

// 10 minutes and 5 seconds
TimeSpan(0, 5, 10).total("seconds") // 605
TimeSpan(0, 5, 10).total("minutes") // 10

TimeSpan.prototype.get

get(unit)

Returns the number of unit in the TimeSpan which is no greater than the next largest unit.

// 10 minutes and 5 seconds
TimeSpan(0, 5, 10).total("seconds") // 5
TimeSpan(0, 5, 10).total("minutes") // 10

TimeSpan.prototype.format

format(formatString)

Formats the TimeSpan with the specified string, the following will be replaced:

l - milliseconds
s - seconds
m - minutes
h - hours
d - days

Those letters will be replaced with the equivalent of doing TimeSpan.get. If you want TimeSpan.total prefix them with a ^.

For padding numbers with zeros, you can have many letters repeated and TimeSpan will use that as the minimum length of the number.

If you want to put the actual letter in the string without it being replaced or a ^ before one of those letters, ~ is the escape character.

TimeSpan(0, 28, 7, 5, 1).format("^hh:mm:ss") // 29:07:28
TimeSpan(0, 28, 7, 5, 1).format("zzz ~^~h~h~hh ^ ~^h ~^~h~h~h^h ^hhh hhh zzz") // zzz ^hhh4 ^ ^4 ^hhh52 052 004 zzz
