Time complexity:

O(N*K)+O(M*log(M)) worst case with N being the smallest input sorted set, K being the number of input sorted sets and M being the number of elements in the resulting sorted set.

This command is similar to ZINTERSTORE, but instead of storing the resulting sorted set, it is returned to the client.
