Why is the salesforce datetime format different in the UI and DB?

243    Asked by DavidEdmunds in Salesforce , Asked on May 15, 2023

Why is there a datetime format so different as compared to what I see in the UI vs SOQL/APEX and I can not figure out what is going on. Can anybody please explain what I'm doing wrong here?

In the UI this is what I see:
5/27/2021 6:30 AM
and when I query I see this:
2021-05-27T11:30:00.000+0000
when I ran the apex code I see this:
2021-05-27 11:30:00
String data = '2021-05-27T11:30:00.000+0000'; Datetime dt = (DateTime)JSON.deserialize('"' + data + '"', DateTime.class); system.debug( dt);

My question, why is it not showing what is in the UI?

The UI format is just a more user-friendly format, shown in your preferred time zone, converted from GMT on the back end.
The results of your query are the IS0-8601 format, how it is stored on the back end.
The output of your Apex code is the default formatting of the Datetime primitive data type.
