I'm trying to use the mailchimp export API in order to keep our internal database in sync with a list we've got in mailchimp.
To do this, I am using the mailchimp export API https://apidocs.mailchimp.com/export/1.0/. According to the documentation, you can pass a since parameter, which I have done with success, but only when I pass a date like this 2015-10-01, but I would like to add a a time factor to it.
I've tried UTC, as well as various other formats.
Does anyone know how to format a date time value for this since parameter?
