PVC pipe glue question

If the consistency seemed fine and it doesn't leak...don't worry about it.

As long as it was useable I think you'll find it will work just fine. I've used it years old and when it got thick I thinned it with lacquer thinner and all went well.. I think they put those dates on so people will spend more money. You know the usual American, RIP OFF>

I used some partially set (gummy) glue to do a non-essential oudoor project under my deck and it did just fine. Yours should be no problem at all.

Paul,

As long as the cement was still fluid (not gelled) it should work as good as new. I recommend tossing the cement when it starts to gel, but I have used partially gelled cement in a pinch without any noticeable issues.

Generally, the cement will keep a long time unless you open the can. Then the air in the can lets it start gelling. That's why I prefer to buy several smaller cans instead of a single large one. I can use the small can for the occasional odd job, and use a new can the next time I need to do something. The larger cans only make sense if you have a big project, like plumbing a whole house, or if you do plumbing work frequently.
