Given:

• I added a non-nullable foreign key to a table.
• I settled on a way to populate the foreign key with default values.
• I checked in both changes to a re-runnable DB creation script.
• Other developers ran this script, and now they have the foreign key populated with default values on their developer machines.

A few days later however...

• I changed my mind.
• Now I'd like to populate the foreign key's default values differently.

My Question:

Can SQL Server or INFORMATION_SCHEMA tell me when SQL objects were created?

Ideally, I'd like to drop and re-add the foreign key if it was created before a certain date/time.

Any help or alternative strategies would be greatly appreciated.
Obviously, I'd like to avoid going to each developer's cube, asking them to drop the foreign key manually.
