getBlockNumber() will not work properly for Arbitrum due to block.number
According to Arbitrum (Docs)[https://developer.offchainlabs.com/time] block.number returns the most recently synced L1 block number. Once per minute the block number in the Sequencer is synced to the actual L1 block number.When on Arbitrum, it cannot retrieve the correct block.number.
Use block.timestamp rather than block.number
