在使用商家转账功能时，发现如果用户正常确认收款，微信回调消息验签正常，如果是超过24小时用户未确认，微信回调消息会验签失败，验签失败的消息：{"id":"03e8aa7e-daa4-5750-8d46-efdbd5da6f58","create_time":"1970-01-01T08:00:00+08:00","resource_type":"encrypt-resource","event_type":"MCHTRANSFER.BILL.FINISHED","summary":"商家转账单据终态通知","resource":{"original_type":"mch_payment","algorithm":"AEAD_AES_256_GCM","ciphertext":"HBzQWjCKZ6lsOsIASMHh/0eXYfEtFH9zajTKIsiYFExCmMT0gNmgezcbQiW1gqWZ/R7f3d6WrPSrGuKGjsvtJfIgR9o/r/tgBeDzOjEyPsYEaVZ+Fmw4bQMUBb0jqlYII/2SaBK63WnWwvgbb3CeCChNLrgRYrwR22lW81Sp8DVUO/jZmL9K22x3HChXeoiH1eqCsr3p+TuNcYr04e6E07zn++HhNJ0mYRGgUXj00ydUlr1j3ix1BPX33SH/CmU9gmOLs7MzQpszD7ZxmkOslwS5bQpe97U6aY03sAEsZm+LyTmlXKh7aEo28WJILVjGkgSFUQL/N48pzHre/oNwIZi2g5Cgwk4K+LLoNXiBBZfxiMSrstK2C4RcxtPPzTusH52MjTQvFoL24mb4Q2xeT3Af43MVMOVIFt8eNVrBBwkzouhrYs2gVdri0xt8QrEoHDC+edY=","associated_data":"mch_payment","nonce":"wYl450lq5OOh"}} 发现明显不对的是create_time，但是header上的时间戳是对的 Wechatpay-Timestamp:"1739590941"
