Trello Todo-Block Due Dates Showing Incorrect Day

[Dan-Peck]

Todo Blocks, particularly Trello (and likely Google Tasks) may end up shifting their TimeZone setting on a cards' Due Date, causing the date to show a day too early (or late) on the Screen under certain scenarios.

In this case, Australia/Sydney was the TZ, and the due date was showing as a day earlier than it should have been.

The code is inadvertently stripping the TZ off from the UTC value of the due date prior to converting it to the selected timezone, causing the improper shift in time. Changing this to skip conversion and go directly to Epoch seconds will correct this scenario.
