当生成日期标头字段时，发件人应生成其字段值作为日期和时间的最佳可用近似值消息生成.从理论上讲，日期应代表在生成有效负载之前的那一刻.实际上，日期可以在消息发起期间的任何时间生成.

When a Date header field is generated, the sender SHOULD generate its field value as the best available approximation of the date and time of message generation. In theory, the date ought to represent the moment just before the payload is generated. In practice, the date can be generated at any time during message origination.
