Gateway_FinalizeBlock
Block timestamp → commit, incl. the gateway-build-block call for block #673
Measured from on-chain timestamps only: the EVM block timestamp, which the producer chose when it planned the block (whole seconds), and the record time (commit) of the Gateway_FinalizeBlock transaction; a commit that reads slightly before the block timestamp (rounding) shows as 0. The gateway-build-block external call runs inside that transaction and is not timed on its own; the import into the execution layers follows the commit and its time is not observable here, so those steps are markers without a duration.

block timestamp → record time (±1s)
Measured from on-chain timestamps: the EVM block timestamp, chosen when the producer planned the block, and the record time (commit) of the Gateway_FinalizeBlock transaction. The block timestamp is whole seconds and follows Canton's ledger time, so the span carries up to ±1s of rounding; a commit that reads slightly before the block timestamp shows as 0.
