Today I added support to IndieNews for storing and displaying the timezone of submitted posts. Previously, all the dates were stored and displayed as UTC, which can be misleading such as when a post is submitted after 5pm in Pacific time since the post then has the date of the following day in UTC.
When you submit a post to IndieNews, you just have to make sure you include a timezone offset in your dt-published property. If you format your published property with a full ISO8601 date such as "2017-02-01T08:40:00-0800" then it is already included.
As with all my projects, IndieNews internally stores the date as UTC, and stores the offset separately. This allows normal date sorting using the one value, and when I go to display the date, I include the offset which adjusts the date appropriately.
