I have the time as milliseconds, but I want the time after conversion like 00:00:00 . Ex: In milliseconds=86400000. I want how many hours in that milliseconds like, 00:00:00 How to get it in JavaScript? Dusht How about doing this by creating a function in javascript as shown below: function msToTime(duration) { var milliseconds = parseInt((duration % 1000) / 100), seconds = Math.floor((duration / 1000) % 60), minutes = Math.floor((duration / (1000 * 60)) % 60), hours = Math.floor((duration / (1000 * 60 * 60)) % 24); hours = (hours < 10) ? "0" + hours : hours; minutes = (minutes < 10) ? "0" +

How to convert System.currentTimeMillis(); to seconds? long start6=System.currentTimeMillis(); System.out.println(counter.countPrimes(100000000)+" for "+start6); The console shows me 5761455 for 1307816001290 . I can't read how many seconds that is. Any help? Nico Huysamen long start = System.currentTimeMillis(); counter.countPrimes(1000000); long end = System.currentTimeMillis(); System.out.println("Took : " + ((end - start) / 1000)); UPDATE An even more accurate solution would be: final long start = System.nanoTime(); counter.countPrimes(1000000); final long end = System.nanoTime(); System

Convert UTC date into milliseconds

问题 I am not interested in what the current UTC time is in milliseconds, nor do I need to mess with timezones. My original date is already stored as a UTC timestamp. I have a date stored in a database in UTC time, "2012-06-14 05:01:25". I am not interested in the datetime, but just the date portion of the it. So, after retrieving the date in Java, and excluding the hours, minutes, and seconds - I am left with "2012-06-14". How can I convert this into UTC milliseconds? 回答1: EDIT: I'd missed the

问题 How can I get the time in milliseconds in Perl without installing any extra package? I am running Linux. 回答1: Time::HiRes has been part of the core since Perl 5.7.3. To check for its availability, check for the Perl version, perl -v , or try to use it with perl -e 'use Time::HiRes;' , both from the command line. Sample usage: use Time::HiRes qw/ time sleep /; my $start = time; sleep rand(10)/3; my $end = time; print 'Slept for ', ( $end - $start ) , "\n"; To build on Konerak's comment, if it

PHP — Convert milliseconds to Hours : Minutes : Seconds.fractional

佐手、 提交于 2019-11-27 14:57:43
问题 I've got a script that takes in a value in seconds (to 2 decimal points of fractional seconds): $seconds_input = 23.75 I then convert it to milliseconds: $milliseconds = $seconds_input * 1000; // --> 23750 And then I want to format it like so: H:M:S.x // --> 0:0:23.75 Where 'x' is the fraction of the second (however many places after the decimal there are). Any help? I can't seem to wrap my mind around this. I tried using gmdate() but it kept lopping off the fractional seconds. Thanks. 回答1:

How to get milliseconds from LocalDateTime in Java 8

不羁岁月 提交于 2019-11-27 10:28:27
I am wondering if there is a way to get current milliseconds since 1-1-1970 (epoch) using the new LocalDate , LocalTime or LocalDateTime classes of Java 8. The known way is below: long currentMilliseconds = new Date().getTime(); or long currentMilliseconds = System.currentTimeMillis(); Stuart Marks I'm not entirely sure what you mean by "current milliseconds" but I'll assume it's the number of milliseconds since the "epoch," namely midnight, January 1, 1970 UTC. If you want to find the number of milliseconds since the epoch right now, then use System.currentTimeMillis() as Anubian Noob has

How to get millisecond and microsecond-resolution timestamps in Python [duplicate]

This question already has an answer here: High-precision clock in Python 13 answers I finally figured this out and would like to share the knowledge and save someone a bunch of time, so see my answer below. However, I still need answers for Linux, so please answer if you know, as my code in my answer is for Windows only. UPDATE: I've figured it out for Linux too, including for pre-Python 3.3 (ex: for the Raspberry Pi), and I've posted my new module/code in my answer below. My original question: How do I get millisecond and microsecond-resolution timestamps in Python? I'd also like the Arduino

What is the duration of a Toast LENGTH_LONG and LENGTH_SHORT

▼魔方 西西 提交于 2019-11-27 08:10:11
I need the exact duration of LENGTH_LONG and LENGTH_SHORT in milliseconds (ms). Also I need to know if the duration of Toast message with LENGTH_LONG will have the same duration in any phone and with any API version. Does someone know where is the duration defined ?, I mean defined in ms . I know that LENGTH_LONG is some int const with value 1. But I could not find where is the actual duration defined. Lars Answered here . Like you mentioned Toast.LENGTH_SHORT and Toast.LENGTH_LONG are not in ms but 0 or 1. The actual durations are: private static final int LONG_DELAY = 3500; // 3.5 seconds

Get current time in milliseconds using C++ and Boost

In my thread (using boost::thread) I need to retrieve the current time in ms or less and to convert into ms: Actually, reading here I've found this: tick = boost::posix_time::second_clock::local_time(); now = boost::posix_time::second_clock::local_time(); And seems to work, but after I need to have a long value of the milliseconds of the now... How can I do it? mkaes You can use boost::posix_time::time_duration to get the time range. E.g like this boost::posix_time::time_duration diff = tick - now; diff.total_milliseconds(); And to get a higher resolution you can change the clock you are using

Sleeping for milliseconds on Windows, Linux, Solaris, HP-UX, IBM AIX, Vxworks, Wind River Linux?

问题 I have to write a C program which has to sleep for milliseconds, which has to run on various platforms like Windows, Linux, Solaris, HP-UX, IBM AIX, Vxworks, and Windriver Linux On Windows, the Sleep system call will work on milliseconds only. On Linux, sleep will work on seconds; usleep will perform on microseconds and it's available on Solaris also. In Vxworks, I hope I can implement using taskDelay and sysClkRateSet . How can I achieve this millisecond sleep on HP-UX, IBM AIX and Wind
