Upon upgrading to 1.0.2, I began noticing that any newly created Resources were being given a default Publish Date of ~30 days into the future. This was preventing me from publishing the resource today without first having to remove the future Publish Date value.
I was able to track the issue down to the use of ManagerManager plugin and the default "mm_demo_rules" chunk from the 1.0.2 installer.
For those of you experiencing this issue, the fix is quite simple:
In "mm_demo_rules" chunk, just comment out the line responsible.
Change:
to:
//mm_default('pub_date');
