Hello Matt and welcome to the forums!
I hope Grocery CRUD will help you out with your programming quests.
Grocery CRUD in general I would call it as a simple, easy and very quick way to add,edit and delete database records.
For these services Grocery CRUD does the job quite successfuly.
Grocery CRUD is using behind the scenes a PHP based framework called CodeIgniter (see here for more information).
Now, if we try to be more specific to what you ask,
1) please define the automatic part; does it mean that the row needs to be created without user intervention? If yes then you need to know if the system that supplies the data can somehow initiate either a script or a connection to the database or even talk to Grocery CRUD(via HTTP connection) and open up the add (record) and populate the data and save to the database
2) for the automatic part of the question see point (1). for the addition of date and time, please explain. isn't this supplied either way from an external source or a user? if you mean to save by default the current datetime, this ability can even be programmed within your database and Grocery CRUD needs not to worry about it at all. but of course even Grocery CRUD (basically PHP) can auto generate and store current datetime to a field(s). what you do with the data later, e.g. charting this is up to you (developer) to build and show
3) I honestly don't understand the question. But I believe this is (partially) answered from the above points (1) and (2). The part of easiness depends also on the complexity of your system! if your database table(s) have e.g. 20 fields that need to be user edited then here is your complexity and there qoes away the easy part. so I can't answer this unless I see your database. if it is let's say a 5 field form (table), even if the form has the worst design it is still very easy to fill in!
I hope these help you to clarify a bit better the magnitude of the task you are about to undergo.
