STEPM._transfer(address,address,uint256) (#1241-1334) uses timestamp for comparisons
Dangerous comparisons:
- transactionTime == true && lastTransactionTime[sender] <= block.timestamp - holdTime (#1271-1272)
- transactionTime == true && lastTransactionTime[recipient] <= block.timestamp - holdTime (#1308-1309)
Avoid relying on block.timestamp.
