Feature #15

[walmik]

@kerro Firstly thank you so much for taking the time to build this out! It's a very important feature and has been a while since it s pending and no one (including me) had taken a stab at it.

Secondly I think you ve directly edited the transpiled timer.jquery.js file from the dist directory. Ideally the changes should be done within the files in the src folder. It involves writing the code in ES6 and using webpack with babel to transpile it. The npm run tasks required to do this are all available for in this repo itself hence it should be straight forward. Please let me know if you are comfortable with doing this PR in ES6. (I believe you will be able to) If not, I can help (Soon I ll add a How to contribute file in this repo). It s really easy for me to take these changes and do it all myself, but I really want you to be associated with this change in the git history :)

Lemme know your thoughts and thanks again for taking up this long-awaited feature for development!

[kerro]

I already did it like you said using webpack.
The changes are done in src.

Terribly silly of me

I ll go through these changes and play with it a bit and get back later today with comments.

[walmik]

Please rename this to DAYINSECONDS

I ve reviewed this PR and suggested some minor improvements. Aside from that this looks great. Once you update this PR with the suggested changes, I ll merge it right in. May I also ask you to please bump the version to 0.6.0 as this is a new feature addition?

[kerro]

I updated files in dist directory ;-)

Looks great 👍 thank you very much @kerro !
