Well, they're handing over the URL prefix hashes, which Tencent uses to look up the real URL list that it returns to Safari. Conveniently, Tencent can also log this hash/list identifier and use whatever algorithms it likes to build a user profile.
I doubt Apple is actually "handing over IP addresses" - rather it's a feature of connecting directly to Tencent via the IP internet. Though they could conceivably provide some sort of proxying, caching, and batching if they wanted to improve privacy.
Similarly Apple isn't "handing over the timestamps" - Tencent can just look at the clock.
