countdown timer background

　 Recently in the mobile to get the verification code countdown problem, found a problem, that is, when the screen hibernation or the program switch to the background, the iOS system countdown will be paused, but in the use of this is definitely a bug. My choice is to get the current timestamp to solve this problem, the specific code analysis is as follows: fun

Problem description: A program was developed to regularly send emails a few days ago. In actual use, it was found that the email was not sent after the scheduled completion time. The mail is sent by the background thread of Asp. Net. The specific method is to send mails one by one at a specified interval through a global Timer. Because the number of emails to be sent is large and the number of mails sent pe
