Does Flow have any equivalent constraints on block timestamp drift similar to Ethereum nodes?

What are the best practices on flow for working with timestamp securely?
Currently Flow doesn’t provide guarantees on the deviation of the block timestamp (see docs), but we have this in the pipeline and expect to support block timestamp as a coarse-grained time-keeping mechanism similar to how Ethereum works today.
