邮件发送时间

Before the invention of the postage stamp, letters were 'franked'. This meant that it was marked on the letter that delivery had been paid for. This could have been either written or stamped. A post-mark was also stamped on the letter. Invented in 1660 in England, this was a mark that showed where and when the letter had been posted. It was used to see how long it took to deliver the letter-to make sure the service was reliable.

在邮票发明之前，信件被用来做印记的，这就意味邮件付费了才能在你的信上标记号，可以用手写，也可以做印记，那么邮政记号也会被印到这个信上，在1660年英国发明邮票之前，那么有一个记号会显示哪里什么时候这个信寄出，那么主要用来发送这个信多长时间来确保这个服务可靠性。
