In a Zope / Zeo configuration (2.7.6), is there a way, on the Zope instance, to know when the database (Zeo) was last packed ?

Publicly, maybe not, but there'll definitely be away to find it out since the pack machinery checks this.
Sorry, pack times aren't recorded anywhere, period. In a FileStorage, each transaction record has a status byte, and that byte is set to a special "this transaction was packed" value the first time the transaction is in fact packed. That's how "the packing machinery" knows whether it's been asked to pack a transaction that's already been packed. The packing machinery has no idea _when_ a transaction was packed, it knows only whether a given transaction _has_ been packed. I suppose you could write a script to rummage through a Data.fs file, searching for the transaction with the largest tid that has been packed, or search for the transaction with the smallest tid that hasn't been packed. tids normally bear a close relationship to wall-clock time, but that's not necessarily true either.
