https://www.pingdom.com/blog/page-load-time-really-affect-bounce-rate/ , the conventional wisdom has been more like two seconds (Google's recommendation), whereas the average website takes 3.21. The drop-off is much steeper than you suppose, based on their charts: You've lost a quarter by 4 seconds, half by 7 seconds. Also, this was in 2018, and I would suspect that people's expectations of their Internet speed have gone up since then (despite average page size also growing).

I think there's room on mobile to have hour rows with 15-minute buttons. Hour rows are readable and scannable so users should be able to skip down to their hour.

I need to cut the last second.SELECT date_trunc('seconds', now()::timestamp);

We can use it. getTimestamp()in order to obtain the number of seconds (since 1970).$diff = $dateTimeLater->getTimestamp() - $dateTimeBefore->getTimestamp()

Since the Double type is used in Delphi to store the date/time, it is possible to read the time value of the variable type double. And then try to convert System.DataTime C#. For example, try this: Double dbl = 65985.3333; //Значение прочитанной переменной из бинарника. DateTime dt = DateTime.FromOADate(dbl)

I've done the task quite elegantly.Since JS can't define a local time zone, but can format unixTimeStamp In local time, we'll have to forget the transfer of the formatted timeline from the server and hand it over to the client. unixTimeStamp for subsequent localization by JS. To make local time filling less visible to the user, as well as the code on the server, do not change, together with unixTimeStamp We'll always give time to Greenwich.Order That's right.1 In the PHP, the time is always Greenwich, using it. gmdate()and appointed dateTime component, contentsinnerHTMLwhich will need to be formatted. In one of the attributes of this element data-date-time♪ data-date♪ data-timeplaced unixTimeStamp depending on what we need to format it.<p>Дата со временем: <span class="dateTime" data-date-time="<?=$date?>"><?=gmdate('d.m.Y (H:i)',$date)?></p> <p>Дата: <span class="dateTime" data-date="<?=$date?>"><?=gmdate('d.m.Y',$date)?></p> <p>Время: <span class="dateTime" data-time="<?=$date?>"><?=gmdate('H:i',$date)?></p> 2 In the numerical prototype JS, we define suitable methods for time formatting and define a convenient function dateTime()which, once the document is downloaded, will receive all elements that need to be formatted and replace their time/date/date over time, whichever is the place unixTimeStamp Greenwich for local time. Call for our function. dateTime() after the completion of the downloading of the document.<script type="application/javascript"> <!-- 'use strict'; Number.prototype.time=function() { return new Date(this*1000).toLocaleString('uk',{'hour':'numeric','minute':'numeric'}); } Number.prototype.date=function() { return new Date(this*1000).toLocaleString('uk',{'day':'numeric','month':'numeric','year':'numeric'}); } Number.prototype.dateTime=function() { return this.date()+' ('+this.time()+')'; } function dateTime() { let doc=document.getElementsByClassName('dateTime'); for(let l=doc.length,i=0;l>i;++i) if(typeof doc[i].dataset.dateTime=='string') doc[i].innerHTML=parseInt(doc[i].dataset.dateTime).dateTime(); else if(typeof doc[i].dataset.date=='string') doc[i].innerHTML=parseInt(doc[i].dataset.date).date(); else if(typeof doc[i].dataset.time=='string') doc[i].innerHTML=parseInt(doc[i].dataset.time).time(); } window.addEventListener('load',dateTime); //--> </script>

What do you think equals? 10000000 * 300? You think 3000000000? No, it's in. int not placed, so the cut will be completed. ♪ ♪Inspired, clearly, this is... long long:liDueTime.QuadPart = -(10000000ll * 300ll); By the way, the compiler was supposed to give a warning! Did you see him?

For the general case of regular update of the variable.private volatile LocalDateTime dateTime; void init() { ScheduledExecutorService service = Executors.newScheduledThreadPool(1); service.scheduleAtFixedRate((() -> dateTime = LocalDateTime.now()), 0, 1, TimeUnit.SECONDS); } A one-time task, with the necessary delay, can be created for the reminder:void init() { ScheduledExecutorService service = Executors.newScheduledThreadPool(1); int delay = 100; // таймаут в секундах до наступления уведомления service.schedule(this::doNotify, delay, TimeUnit.SECONDS); } void doNotify() { // тут выполняем логику уведомления }

I used Google Maps. API https://maps.googleapis.com/maps/api/timezone/json access to the current temporary zone at the specified coordinates (including time transfer). The city's coordinates are easy to get by name.Here's the documentation. https://developers.google.com/maps/documentation/timezone/intro Look at the parameters dstOffset and rawOffset.

JavaScript has a function. Date() Use it for time and time. All useful information can be obtained: https://learn.javascript.ru/datetime To get the difference, we'll first get the current numerical time:var millseconds = +new Date; We'll transfer milliseconds in the clock.var hours= millseconds/(3600 * 100); Next summer in Date Method:var millseconds_next = +new Date(2017,5,1); We're also transferring millions in the clock:var hours_next = millseconds_next/(3600 * 100); Our difference in watch is the time:var next = hours_next - hours;

Here's my decision:ui->label->setText(trUtf8("Дата сборки программы: ") + __DATE__ + trUtf8(" в ") + __TIME__);

Something like that:if (QTime::currentTime().hour() == 18){...}

public class MainActivity extends AppCompatActivity { private TextView mTimeTextView; private Button mTimeButton; private Calendar mStartTime; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mStartTime = Calendar.getInstance(); mTimeTextView = (TextView) findViewById(R.id.time_text_view); mTimeButton = (Button) findViewById(R.id.time_button); mTimeButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Calendar nowTime = Calendar.getInstance(); long secs = (nowTime.getTimeInMillis() - mStartTime.getTimeInMillis())/1000; mTimeTextView.setText(String.valueOf(secs)); } }); } }

I'll try to answer in a simple language. ♪ ♪It's not. time.h♪When you announce any variable, at least the best. int i - you're basically saying, "I need a piece of memory in which I'll keep the type of thing. int and I will call i" This place is yours. But for local variables (pledged into functions) for efficiency, the compiler simply provides memory. and everything. - it doesn't matter.When you've just described your variable, which, once in a while, will be stored for a while, everything that's done is a piece of memory in the glass. Now it's your job to tell you what to fill. Same as before using the same. int iShe's got to take some weight out of it. It's got to be something accidental in her memory from other variables or even other programmes.How to fill out another question, time.h related functions (and many books, handbooks, etc.) are described.One more. very insistent. You don't have to ask the picture. Is it so hard to copy the text? Harder than taking a copy of the screen? :

If the original mass is cutting the full date, then we shall minimize this step and form a set of keys unix_timestamp from start and unix_timestamp from end. Then we'll sort it out on the key and we'll do all the work.If the initial data is exactly HH:mm, then the same is the same, but the keys/digits are formed as HH*60+mm

Converting the date in the line toString() uses the challengeQLocale::system().monthName(month, QLocale::LongFormat); QLocale uses masses in the process static const ushort months_data[] // qlocale_data_p.h static const QLocaleData locale_data[] It's not gonna be possible to add the end. So either write your function or retrieve the Qt from the originals by altering sets.

It's really wrong to abandon this type of data. He's comfortable enough:Necessary data:time_t r_time; struct tm * time; char buffer [100]; Initiated:r_time= time(0); time= localtime (&r_time); Used the excellent strftime function: (cf. standard)strftime (buffer, 100 ,"%Y-%m-%d %H-%M",time); puts (buffer); I think that's it.

QueryPerformanceCounter and QueryFrequencyCounter can be used under Windows. If you don't need the most accurate timer, you can use the GetTickCount.To measure the time of the section, keep the time before it and calculate it from the time that it was received immediately after the code was completed. In order to determine the time, it is desirable to repeat the code in the cycle several times, and the result is to divide the number.

In php, there's a built-in DateTime class to work with dates/periods of dates and stuff. which makes it possible to use even this syntaxy. $firstDayOfPastMonth->modify("0:00:00 first day of previous month");For a sausage of dates, of course, http://php.net/manual/en/datetime.createfromformat.php Example from there:$date = DateTime::createFromFormat('j-M-Y', '15-Feb-2009'); echo $date->format('Y-m-d'); You can use whatever you want and choose, and you can invent strtotime bicycles only when you need to dissolve something in UNIX timestamp, it's only for that.
