Why is ATT Posting the wrong KQED schedules

For the last several weeks the KQED  program listings at least for the evenings do not match what is posted on KQED.org.  For example, it lists Masterpiece at 10 pm Sunday when in fact it is shown at 9 pm;  The new series Crimson Field isn't listed til after midnight; when in fact it is broadcast at 10 pm.   And now Last Tango in Halifax, which on KQED.org says it will be on at 8pm ... other programs are showing on the Uverse channel guide at 8.  It makes it VERY hard to record programs.
