Adapting block.timepoint to the new form also adapts withdrawal_block_timepoint, deposit_block_timepoint, and stake_block_timepoint, which must all be equal to block.timepoint.
The global state should have the last_finalized_timepoint equal to the input.since, do not add the finality_time_in_ms.

"is_block_finalized_withdrawal_cell" is more confusing for me. How about "is_legacy_withdrawal_cell"?

The PR brings two major changes:
The interpretation of both the block timepoint change from occurance block timestamp to future finalized timestamp, as well the global state last finalized timepoint change from last finalized timestamp to current timestamp.
You can see the differences via diff:
let block_timepoint = { if fork_config.use_timestamp_as_timepoint(block_number) { - Timepoint::from_timestamp(block_timestamp) + let finality_time_in_ms = rollup_config.finality_time_in_ms(); + Timepoint::from_timestamp(block_timestamp + finality_time_in_ms) } else { Timepoint::from_block_number(block_number) } };let last_finalized_timepoint = if fork_config.use_timestamp_as_timepoint(block_number) { - let finality_time_in_ms = rollup_context.rollup_config.finality_time_in_ms(); - Timepoint::from_timestamp(block_timestamp.saturating_sub(finality_time_in_ms)) + Timepoint::from_timestamp(block_timestamp) } else { let finality_as_blocks = rollup_config.finality_blocks(); Timepoint::from_block_number(block_number.saturating_sub(finality_as_blocks)) };Note that
WithdrawalLockArgs.withdrawal_block_timepoint,CustodianLockArgs.deposit_block_timepointandStakeLockArgs.stake_block_timepointis also block timepoint.Check v2 withdrawal cell finality based on input since.
Without replying
GlobalState, or say rollup_state_cell, we still can check a v2 withdrawal cell finality based on input since, so that avoid celldep-race issue.Proposal for further changes:
Timepoint::BlockNumbertoTimepoint::Lagecy,Timepoint::TimestamptoTimepoint::NewGlobalState.lats_finalized_timepoint,WithdrawalLockArgs.withdrawal_block_timepoint,CustodianLockArgs.deposit_block_timepointandStakeLockArgs.stake_block_timepoint.This PR will not make these changes, since I am having some problems bumping gw-types in the "develop" branch.
