Currently there's an option to show/hide the time, but there isn't one to show/hide the date. This will help with instances where the date isn't as relevant as time. For example, a fire call has a number of timestamps that capture when a call comes in, when it's dispatched, when a unit is en route, when it's arrived, etc. All this happens within minutes. Turning off the date of a datetime field would help visually clean up the table.
I imagine a toggle similar to the existing "Show time" under Configure Fields
