Are your arrays running flare 29? If so, then see:  EMC Technical Advisory emc288699: CLARiiON CX4 Series and Celerra NS Series: Leap year display issues on arrays running FLARE Release 29.  glen  ps - on March 1st the problem goes away
Both my SP's on Both Arrays (Same Domain) cannot keep their date and time all of the sudden.  What is the cause of this?  I tried setting manually and they lose it right away.  What does this mean?
SP'S Cannot hold Date or Time
