I just installed an eval copy of windows server 2012 (datacenter) core.
It says its a 180 evaluation, but checking the licensing info I see this:
Is this different for core installs than GUI because I have used the same iso to do full GUI installs and it always gives me 180 days.
I should also add when downloading the trail I was not provided a license key.

You never activated it online...you have to do that to allow for the full 180 days.
