Description:
In a Date control, in design mode, if try to set "Date max" property to a value greater than 1/1/9999 it changes to 1/1/9999 without any warning. Also is is not possible to delete "Date max" value.
So, in production, the maximum date that is possible to introduce in a date control is 1/1/9999.

Steps to Reproduce:
1. Create a writer document (or a Base form, or a Basic form, or may be in Calc or Impress)
2. Insert a Date field control
3. In design mode, set "Date max" property value greater than 1/1/9999
4. Lost focus on "Date max" property, the value is changed to 1/1/9999 without any warning
5. Close design mode
6. Introduce a date greater than 1/1/9999 and push Enter, the date is changed to 1/1/9999 without any warning


Actual Results:
* Not possible to set a greater than 1/1/1600 "Date max" property value
* Not possible to introduce a value lower than 1/1/9999 in a date field control


Expected Results:
* Set any "Date max" property value, also no value (no limit) or at least from "1/1/0001" to "31/12/9999" which is the range in most of databases
* Introduce any date in the control


Reproducible: Always


User Profile Reset: No



Additional Info:
Now it is not possible to introduce a date like 9/9/9999. This date is used frequently by database users to indicate a "no date" value or the last value (no end) in a "from-to" combination of values.
