mm I think that you would need to have separate formula column for this (different formulas for different output).
So lets say your column with date is called 'Date’
and in this column you have a following value:
2016-07-04 14:55:00
then you can have a formula column called ‘Formula’ with this in formula field (as an example):
DATE_FORMAT(Date,'%b %d %Y %h:%i %p')
Then in ticker appearance tab you would double click the ‘Formula’ to show it on the layout and it will take the date from your Date column and ‘convert’ it and display this on the layout: (in this example:)
