* market: use `pending` blocktag when querying onchain state * clock: use wall clock in integration tests reason: we'll need to wait for the next period in integration tests, and we can't do that if the time doesn't advance * clock: remove unused field * integration: use pending block time to get current time * clock: fix on-chain clock for hardhat Only use 'latest' block for updates Only update the first time you see a block * integration: do not start tests with a very outdated block * integration: allow for longer expiry period
