It's just a "date"-field without time.
  ALTER TABLE entwurf.objekt ADD COLUMN von date;
  COMMENT ON COLUMN entwurf.objekt.von IS 'Beginn-Datum';

> which timezone is configured in PHP

echo date_default_timezone_get();
Shows: " Europe/Berlin "

PostgreSQL :
/etc/../postgresql.conf was changed now from
  #timezone = unknown # actually, defaults to TZ environment
  timezone = 'Europe/Berlin'
whithout any effect.

> might be a timezone configuration problem

My timezone is only 1 h different to UTC. Problems from computing a time from "Berlin" to "UTC" may only appear 1 h +/- around midnight.
But date-Format hasn't any time-component, it's just "year-month-day" which has not to be computed.  

Datepicker puts a string like "2013-02-07" in the textbox of the WFS-Conf.
On the way via GeoServer/WFS to PostGIS it become "2013-02-06" as I can see in pgAdmin.

Reading it back in WFS or WMS-FeatureInfo it is shown as "2013-02-06".
Changing WFS-Conf from
  <input data='{\"dateFormat\": \"yy-mm-dd\"}' type='text' id='von' class='hasdatepicker' />
  <input data='{\"dateFormat\": \"yyyy-mm-dd\"}' type='text' id='von'  />
For Text-Input without datepicker, doesn't fix the problem.

<input type='text' id='von'  />": save is wrong as before, no read back to textfield.

Last try: Using Datepicker without format.
   <input type='text' id='von' class='hasdatepicker />

Picking "Feb. 7th" puts in WFS-Textbox "02/07/2013".
Save to PostGIS and Feature-Info is "2013-07-02 ".
 Hey!  Month and day are confused, bit NO SHIFT!

Maybe the 
  data='{\"dateFormat\": \"yy-mm-dd\"}' 
is not correct?

might be a timezone configuration problem. Depending on which timezone is configured in PHP and time of day the local time might be in a different day than a datetime without timezone (which is assumed to be UTC, I think).

Just where this problem occurs, is beyond me. I would check PHP's configuration and the actual type of the PostgreSQL field for a beginning.
