This enhancement-request comes from a German LO-forum:
When creating a table and define, for example, a field for TIME, there will be a standardformat '00:00:00' (hours:minutes:seconds). 
When creating a form for this table the field in the form has standardformat '00:00' (hours:minutes). Uninformed users would miss the input for seconds here and don't know, that is defined in a different way.

That isn't the only field with different standardformatting. Have a look at a field with INTEGER-AutoValue. This will be created in the form wizard as a decimal with two digits. Every time I create a form by the wizard I have to reset this field to a field without digits.

When creating a form it would be great to get the format from the table. If you want to change this, you could do it later. But if you won't you have excluded one step and the uninformed user isn't irritated about different forms.

Have a look at bug86315 . If this bug is solved you could also read out the format of queries and define the defaultformat of a form, which has a query as datasource.
