Include Time In PostDate/DateTime Field Control Panel Display In Craft 3 if you use a DateTime field and have it set to time only, it still displays as a date in the Control Panel with no time. 

Even if it is used as a date and time field, just like entry post date it will only display time if it's on the current day.

Is there a way to modify this format to include the time in the control panel display?
There's a plugin for Craft 2 that did this called BigDates.

As of 7/19/2018, it's been ported to Craft 3 on the v2 branch, but not tested or added to the Plugin Store yet, so there might still be some issues: https://github.com/pixelandtonic/BigDates/tree/v2
