Wemix Retainer 133 PricePolicy

The `checkMintable()` function contains a discrepancy between its code logic and the accompanying comments. The comment suggests that the function checks if "the timestamp of the TWAP information is more than the current timestamp." However, the actual implementation calls the `isMintableTime()` function, which verifies if the current timestamp is greater than the cached TWAP price timestamp: ```solidity=152 function isMintableTime(uint start) public view returns (bool) { return block.timestamp > start; } ```
