dateFormat - how to get it to this format

[sfdctower]

Hi community,

I'm using the default dateformat which is YYYY-MM-DD hh:mm. This is from https://raw.githubusercontent.com/mugifly/jquery-simple-datetimepicker/master/jquery.simple-dtpicker.js

But do you know how to change the dateformat to align with this one from this system yyyy-MM-ddTHH:mm:ss.SSS+/-HHmm

explained here https://success.salesforce.com/answers?id=90630000000gl7rAAA

Currently my input form on my website is augmented with this javascript, much like the examples on this site: http://mugifly.github.io/jquery-simple-datetimepicker/jquery.simple-dtpicker.html

Thanks so much,
