It would be good if all the dates that are displayed in the Admin were formatted as per that site instance timezone/local. This could be quite confusing for the client.
Alternatively, a site setting that allows us to set a custom date format to be used, ie:
01.30.2019 ( %m.%d.%Y )
30-01-2019 ( %d-%m-%Y )
30/01/19 ( %d/%m/%y )
30 Jan 2019 ( %e %b %Y )
etc…
