If you look at the documentation for .../preapply/block, you see two parameters: sort, and timestamp But there is no explanation for what these do. The RPC help does not even mention them:
$ ./tezos-client rpc list /chains/main/blocks/head/helpers/preapply/block
Available services:
- POST /chains/main/blocks/head/helpers/preapply/block
Simulate the validation of a block that would contain the given
operations and return the resulting fitness and context hash.
Can someone explain what these two parameters mean?
