Note that if you want to input into mysql, the time format needs to be: format("Y-m-d H:i:s. location timestampMs / 1000 This works because there are 1,000 milliseconds in a seconds. $local = $now->setTimeZone(new DateTimeZone('Australia/Canberra')) Įcho $local->format("m-d-Y H:i:s.u"). //Convert milliseconds into seconds by //dividing the milliseconds by 1000. The setTimeZone() method can be used to accomplish this requirement.Īs an example: $now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', '')) However, this should be done as a separate step after the initialisation ( not using the third parameter of createFromFormat()) because of the reasons discussed above. By default, microtime() returns a string in the form 'msec sec', where sec is the number of seconds since the Unix epoch (0:00:00 January 1,1970 GMT), and msec measures microseconds that have elapsed since sec and is also expressed in seconds. If you need to display the time for a particular time zone then you need to set it accordingly. I have a subtitle files in which i have starttime and endtime which is formatted like this 00:38:42,689 but i dont want this i have functionality of subtitles which work on milliseconds so i want to convert it in milliseconds in php. This means that the DateTime object is implicitly initialised to UTC, which is fine for server internal tasks that just want to track elapsed time. However, the technique described here is initialising the DateTime object using microtime() which returns the number of seconds elapsed since the Unix Epoch ( 00:00:00 GMT). Normally the createFromFormat() method will use the local time zone if one is not specified. $now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', '')) Ī note on time zones in response to DaVe. Too bad it doesn't feel quite as elegant any more. Thanks goes to giggsey for pointing out a flaw in my original answer, adding number_format() to the line should fix the case of the exact second. Php http convert milliseconds to time manual#This produces the following output: 04-13-2015 05:56:22.082300įrom the PHP manual page for date formats: $now = DateTime::createFromFormat('U.u', microtime(true)) GetElapsedTime explicitly before restart.You can readily do this this with the input format U.u. Note that restart also returns the elapsed time, so that you can avoid the slight gap that would exist if you had to call Std::cout << elapsed2.asSeconds() << std::endl Sf::Time elapsed2 = clock.getElapsedTime() Std::cout << elapsed1.asSeconds() << std::endl Sf::Time elapsed1 = clock.getElapsedTime() Example: 15:25:05:03 (This would represent 3:25pm) Just to clarify the millisecond will be similar to what is shown on a. So for example the current time will have Hour : Minute : Second : Millisecond. The time elapsed since the clock started, and restart, to restart the clock. Ren said the following on 15:39: Hi all, I am trying to display the current time including milliseconds (two digits. It only has two functions: getElapsedTime, to retrieve Getting microseconds, milliseconds and nanoseconds then converting them back to current time with PHP - PHP I decided to add this very very simple post to demonstrate how we can get the current time in microseconds, milliseconds and nanoseconds then converting them back to current time again. SFML has a very simple class for measuring time: sf::Clock. Php http convert milliseconds to time how to#Now that we've seen how to manipulate time values with SFML, let's see how to do something that almost every program needs: measuring the time elapsed. Sf::Time is just an amount of time, so it supports arithmetic operations such as addition, subtraction, comparison, etc. Similarly, a sf::Time can be converted back to either seconds, milliseconds or microseconds: Note that these three times are all equal. There is a (non-member)įunction to turn each of them into a sf::Time: It is not a date-time class which would represent theĬurrent year/month/day/hour/minute/second as a timestamp, it's just a value that represents a certain amount of time, and how to interpret it depends on the contextĪ sf::Time value can be constructed from different source units: seconds, milliseconds and microseconds. Sf::Time represents a time period (in other words, the time that elapses between two events). That manipulate time values use this class. Instead it leaves this choice to the user through a flexible class: sf::Time. Unlike many other libraries where time is a uint32 number of milliseconds, or a float number of seconds, SFML doesn't impose any specific unit or
