A bit like with food, this stated shelf-life is more of a guide rather than a hard and fast rule. Inside of the 12 months, we guarantee that the properties of the resin (in terms of its cured mechanicals, pot-life, cure time etc.) will be within tollerance of the published specification. Outside of the 12 month period the resin will often still work and still cure however the cured properties and particularly the pot-life and cure time will start to go outside of tollerance. As stated by the other posters, it's certainly true that the resin itself is far more stable (ours have a 3 year stated shelf-life) but the hardeners are much more sensitive and really do start to go out of specification when they're older. I've certainly used our EL2 and IN2 well out of date and they have cured but as the others have said, if it's a critical part I would at the very least recommend that you replace the AT30 Hardener.
