stopwatch milliseconds

1 second = millisecond = 1000,000 microsecond = 1000,000,000 nanosecond PHP has no default function for milliseconds, but it provides a microtime () function that returns two elements, one for seconds, and one for fractional milliseconds, which makes it easy to define a function that returns a number of milliseconds, for example: /* Get time difference

In many scenarios, developers are accustomed to using the number of milliseconds since the 1970-01-01 00:00:00.000 to represent a specific time, so that data can be stored in the database in numbers type, and at some point convenient to compare, again, sometimes we need to Converting this number of milliseconds into a standard timestamp type now summarizes two implementations:Method One:SELECT to_timestamp

number of seconds after conversion can be used for the next jQuery countdown.CSS We need to give the list on the page a slightly better look. The Code is as follows: Copy code . Endtime {font-size: 20px; font-family: "Microsoft Yahei"; color: #000}. Prolist {margin: 10px auto}. Prolist li {float: left; width: 320px; height: 240px; margin: 10px; font-size: 14px;Position: relative}. Prolist li img {width: 320px; height: 198px ;}. Showtime {position: absolute; top: 174px; h

This article describes how to obtain a timestamp in milliseconds in PHP. it involves php's processing skills for the results returned by the microtime function, which is very simple and practical, for more information about how to obtain a timestamp in milliseconds, see the example in this article. Share it with you for your reference. The specific analysis is as follows: PHP does not provide a function

Php does not provide a function that returns the number of milliseconds, but provides a microtime () function that returns an array containing two elements, one being the number of seconds, one is the number of milliseconds represented by decimals. With this function, you can easily define a function that returns the number of milliseconds. For example:Copy codeT

The most common way to hide a table column is as follows: Copy Code code as follows: Td.style.display = "None"; The efficiency of this approach is extremely low. For example, hiding a column of a thousand-row table, which takes about 4000 milliseconds to execute on my notebook (P4 M 1.4g,768m memory), is intolerable. For example, the following code: Copy Code code as follows: Unfortunately, the way we Google ou

GetTickCount () and GetCurrentTime () are only accurate to 55ms (1 tick is 55ms). If you want to be accurate to milliseconds, you should use the timeGetTime function or the QueryPerformanceCounter function. Specific examples can refer to QA001022 "VC + + using High-precision timer", QA001813 "how to achieve accurate timing in Windows" and QA004842 "timegettime function delay." 　 Operating system: Win2000 Programming Tools: VB6 Problem: I used the ti
