Time displays 00:00:00 for children

In the Individual view, the father and mother display the date in YYYY-MM-DD format but the children still display YYYY-MM-DD HH:MM:SS format, which is almost always 00:00:00 and should probably not be displayed. I tried to make a patch to omit the time part in the view.inc file:

--- view.bak	2010-03-17 22:35:34.000000000 -0600
+++ view.inc	2010-03-17 22:42:21.000000000 -0600
