Steps to reproduce the issue

Enable the sending of Action Log entries to a Super Admin by Mail in Joomla 3.9
Set your Joomla Global Timezone to be something the other side of the world
Generate a load of emails

Expected result

Any reference to the date/time an event occured should be translated to the Joomla Global Configuration Timezone/offset

Or if not it should be explicitly stated what the time zone used is.

Actual result

The date/time right now is UTC/GMT, but a Joomla Super Admin the other side of the world (with a server another third of the way around the world) is confused and assumes its local time, so would be best when giving the date/time to tell the recipient WHAT timezone that timestamp relates to.

Additional comments

Do we really need seconds too???
