tzTime

Copyright (c) 2009-2013, Lawrence S. Maccherone, Jr.

Timezone transformations in the browser and node.js plus timezone precise timeline creation for charting.

Features

• Transform into and out of any timezone using Olson timezone rules

• Timezone rule files embedded in the minified browser package. No need to host them seperately.

• Create timezone precise time-series axis for charts

  • Knockout weekends, holidays, non-workhours

  • Work with timezone precision

  • Work in any granularity

    • Year, quarter, week, day, hour, etc.
    • No more recording 2012-03-05T00:00:00.000Z when you really just mean 2012-03-05
    • Create and use custom granularities: R02I04-07 = Seventh day of fourth iteration in second release

• Tested - Over 450 tests

• Documented - Robust documentation

• DocTested - The examples will always match the code because it fails automated testing when they don't

Used when running:

• timezoneJS - library for Olson tz file parsing. Although I haven't touched the actual tz file parsing code, I have modified timezoneJS fairly significantly. The original included a drop-in replacement for JavaScript's Date object which I have removed. I also modified it to work on node.js and in the browser once "browserified" by bundling the tz files.

Used when developing:

• Node.js
• CoffeeScript
• coffeedoctest (by Larry Maccherone)
• nodeunit
• browserify with fileify plugin (modified)
• uglify-js
• wrench
• marked

Using from a browser

If you are using Lumenize, you don't need to do anything. The browser package for Lumenize includes tzTime. If you just want to use tzTime without Lumenize, then you can either host it on your own site.

Then:

var tzTime = require('./tzTime'); var timeline = new tzTime.Timeline({startOn:'2012-01', endBefore:'2013-01'});

Installation for node.js usage

To install, run the following from the root folder of your project:

npm install tzTime --save

Installation for development

The documentation system uses jsduck so you'll need to install that like this:

[sudo] gem install jsduck
