I understand that in the long run time information is useless (who cares that 25 years ago, something happened at 09:45?), but it doesn’t hurt to include them either.
If this would be a traditional software, my question would be more straightforward: Why don’t you allow the date object to be datetime instead?
Gramps being Gramps, I don’t know how to exactly formulate my question; instead, I’ll leave it a little bit more “open-ended”.
(Please include your Gramps version and Operating System):
Windows 10/Ubuntu / 5.1.3 (if I have added them on my profile, why do I need to again add them here?)
Because it is optional in the profile & most people don’t opt in. Even if they do, it’s too much for the occasional Discourse user to remember they can drill down to discover that info while answering a question.
Why make people do extra effort when you’re asking the favor of help?
Attributes is a tab of records in the Event & Person Editors. (You can also add the built-in Attributes Gramplets with the other tabs in the Bottombar.)
There are a few Attributes management tools & custom filter rules but… since it isn’t predictable data, there are no built in analysis features and they are overlooked in a lot of the reports.
