Milliseconds Handles milliseconds precision (0 to 999).
Seconds Maximum precision is seconds; it does not handle milliseconds (default value).


Generators: Android, Apple, Java, .NET, .NET Core
Level: Attribute, Domain


When Precision is set to Milliseconds, then the DateTime data type field supports storing and displaying the DateTime with higher precision than just 1 second; it then supports fractions of seconds like 3.5 seconds (three and a half seconds), 10.250 seconds (ten seconds with 250 milliseconds) or 5.005 seconds (5 seconds with 5 milliseconds). Such a field is often also called a Timestamp.
