Problem whit the FIELD DATE

Hello everybody!!!

I have problems to use the Date field, this field configuration by default, to see the item and gives me this error.

DateTime :: __construct () [datetime. - Construct]: Failed to parse time string (test text) at position 0 (T): The timezone Could not be found in the database

There is a a problem to Flexicontent or Joomla Configuration.????

In the Global Configuration or Joomla I have:

Server Timezone: Argentina/Buenos Aires

Please Helpmee!!! Thankss!!!

As you can see by the message

... you have entered a value: test text as date this fails parsing and the JDate throws a exception that terminates execution.

new revisions of date field catch this exception and ignore the invalid date, thus prevent the stop of execution
