// proposalStepWaitingTime determines how long a validator should wait for a block
// to be sent from a proposer. This duration is determined as a result of the
// previous block's time as well as by the Accuracy and MsgDelay timestamp parameters.
// The validator's and the proposer's clocks should differ from eachother by at most
// 2 * Accuracy and the proposal should take at most MsgDelay to arrive at the validator.
// The validator must therefore wait at least 2 * Accuracy + MsgDelay for the proposal
// to arrive.
// proposalStepWaitingTime is used along with the `timeout-propose` configuration
// parameter to determines how long a validator will wait for a block to be sent from a proposer.
// proposalStepWaitingTime ensures that the validator waits long enough for the proposer to
// deliver a block with a monotically increasing timestamp.
//
// To ensure that the validator waits long enough, it must wait until the previous
// block's timestamp. It also must account for inaccuracy in its own clock, inaccuracy
// in the proposer's clock and the amount of time for the message to be transmitted.
//
// The result of proposalStepWaitingTime is compared with the configured `timeout-propose` duration,
// and the validator waits for whichever duration is larger before advancing to the next step
// and prevoting nil.
