Timer task, in the Web application is more common, how to use PHP to implement the timer task, there are roughly two scenarios: 1 Use the crontab command, write a shell script, in the script to call the PHP file, and then execute the script regularly, 2 with the use of Ignore_user_abort () and Set_time_limit () to run the script out of the browser. The former is the use of Linux features, and PHP itself is
[Efficiency] Simple tomato timer designed for Win7 systems, simple win7 Timer
Time flies, and it has been almost three years since I tried my best to work with tomato! Persistence for such a long period of time is mainly due to its simplicity. However, for a long time, seven different tomato timers have not been found satisfactory:■ The mechanical noise is too high, which may impede colleagues and can only
With timer interrupt, single chip microcomputer interrupt processing time is greater than timer timing?If the interrupt type is different, it can be nested according to priority, if it is the same interrupt type (such as the title),There are three kinds of results: 1, immediately into the new interrupt processing (interrupt nesting) 2, wait for the interrupt processing and then enter the new interrupt proce

JavaScript compiled a timer, a javascript Timer
A timer is written in JavaScript.
Design Philosophy:
1. Use the Date () object to continuously obtain time points;
2. Subtract the milliseconds between the two time points to calculate the time difference;
3. accumulate the time difference so that the timing can be accurate.
Ps:
