Message:

I hope these are all the changes necessary on the runtime side of GS2 to get the OAI server validation working for GS2: instead of working out the earliest datetime stamp of the OAI repository by comparing the builddate in index/build.cfg of each OAI collection and selecting the earliest, the oai-inf.db is now storing the special earliesttimestamp record. The timestamp of this record represents its collection's earliest timestamp. And the earliest of these among all OAI collections is now the earliest datetime of the OAI repository.
