The Console display the Start Time (and all other time) in "Browser Time" so that the person using it sees it in the time zone they are in (offset is written in parentheses for StartTime).
The Mobile Application displays the time as it was injected, which should be the local time of the Event (standard ticketing).

Example:
Lets say a Ticket is injected for an Event that starts the 2020-01-01 at 20:00 in Lausanne (UTC + 1) the time sent in the injection batch should be "2020-01-01T20:00:00+01". Imagine this event is organized by an English company based in London.
On the Mobile ticket in the app, one will see 2020-01-01 20:00 (as it is always display in the local time of the event).
On the Console the Support Team based in London (UTC) will see Start Time 2020-01-01 19:00 (their local browser time). The purpose of this is that the Support Team see correctly when the event (and other time) will start based on their local time, meaning they won't have to make time conversion every time they look at something.
