I keep the tooth shade for special situations but mainly use white so today when I was bonding a crown, I grabbed the A2. It seemed to take forever to gel and when I checked, it was Jan 2009 expiration. It did light cure fine but it was an eMax crown so I'm not sure if I can trust light to fully transmit.

I did a bench set and it seemed to have some set after about 20 minutes.

Is the expiration date that tight?

It should be OK. It does have some O2 inhibition which is likely what you saw.
