PHP - Time Question

I'm trying to convert the following time stamp: 12:03PM to military time 13:03.

I'm using the following code, but it's just outputing 12:03:
$sampledate=("2010-11-08, 12:03PM CST");

$xplodeDateStamp = explode(", ", $sampledate);
$xplodeDate = $xplodeDateStamp[0];
$xplodeTime = $xplodeDateStamp[1];
echo "Date: " . $xplodeDate . "<br>";
echo "Time: " . $xplodeTime . "<br>";
echo "Military Time: " .  date("H:i",strtotime("$xplodeTime"));

It seems like this is a question that may be on here already, but I couldn't find it with a search, so I apologize.

I am given a string that represents a datetime, and it is always in this format: HH:mm:ss MMM DD, YYYY PDT.

I just want to turn that into a proper format for mysql (Y-m-d H:i:s), but I'm not exactly sure how to go about that. (I could do this in C# rather quickly!)

Probably a simple question, I hope someone can help! Thanks.

I'm interested to know how other people keep track of time and also how they display time correctly back to the users. I'm using a third party API that I can tie into that actually gives me the userID of a user, their full name and the timezone for that user. After checking a few users data, this is an example data of what I'm working with.

userID: 234213412
first_name: foo
last_name: bar
timezone: -6

Basically when a user visits my web app, I create a new account for them and store the above data. Currently, I'm just fetching the result from time() and converting it into MySQL DateTime format and storing that into my database.

Code: [Select]
//get the current time as an integer
$php_timestamp = time();
//formats the time according to MySQL DateTime type
$this->mysql_formatted_time = date('Y-m-d H:i:s', $php_timestamp);

I would think the current way that I'm doing this is not very good because there is a possibility that I could introduce load balancing servers into the mix and they might not be located in the same region. Also, I would have no idea how to factor the time and modify it according to the timezone value.(in my above example, -6)

Can anyone help me decide what method I should use to keep all of my servers timestamps in sync and how to display the time to the end user so that it looks correct to them?

PHP date and time function is not showing correct time on my local system

I have the following php code

date_default_timezone_set("Africa/Lagos");

$date = date('d-m-y h:i:s');

echo "Server Time ".$date ."<br>";

echo "The time is " . date("h:i:sa")."<br>";

$current_datetime = date("Y-m-d") . ' ' . date("H:i:s", STRTOTIME(date('h:i:sa')));

echo "Current time1: ".$current_datetime . "<br>";

 

Output

Server Time 21-05-21 09:55:39
The time is 09:55:39am
Current time1: 2021-05-21 09:55:39

 

Expected Output

Server Time 21-05-21 10:55:39
The time is 10:55:39am
Current time1: 2021-05-21 10:55:3

 

Any help would be appreciated.

Basically I have recently been playing around with parsing a csv file. What I am looking to do at this point is simply take the date/timestamp (part of the csv file), which is in the following format:DD/MM HH:MM:SS.100th/s
For the sake of argument, lets say I have this in an array string called $csv[0] and the file has several lines that span the course of a couple hours. I wouldn't mind having to use explode() to breakup/remove the date or 100th/s IF that would make things a lot simpler.

So where would I start in trying to achieve this?. The result I am looking for will simply return "X Seconds". Storing this in a string variable would be a bonus, as I plan to use this to divide a separate piece of information.

Any examples or ideas would be great. Thank you.

ps:
Here is an example time from the csv file itself:
Code: [Select]
11/19 22:23:18.143

I am trying to simulate an ad expiration and carry out an action if the ad is expired. And I cannot get the if/else to work properly... I've tried many variations and I cannot see what I am doing wrong here. Any tips please 3 hours and counting of no solution!

$ad_start = time()-14 . "<br />"; // 14 days from today in the past (negative)
echo $ad_start;

$current_time = time() . "<br />"; // current epoch time
echo $current_time;

$days_past = $ad_start - $current_time; // days past

echo "<br />$days_past days have past since the ad started!<br />";

if($days_past <= 14)
{
echo "<br />Ad is less than 14 days.  Not expired.";
}
else
{
echo "<br />Ad is over 14 days. Expired.";
}

We rent PHP server space on a server in California. Several of my pages generated by PHP show the current date and time, so when the page is printed, the user knows when the data was printed. Our users could be anywhere in the US, I am in Michigan. How do I convert the server time (PDT) into local time, regardless of where the user is?

Thanks.

Hello,

I tried to implement some PHP code to enable a web page to show "Dinner" specials versus "Lunch" specials based on the time.

The business is located in the Eastern Time Zone, so I only need to routine to work based on Eastern Time (New York).

What I am noticing is that the server is processing the lines of code so fast that the command to establish the correct time for the remaining code is not always being acknowledged.

This line of code appears to be processing too fast for the remaining lines of code:
date_default_timezone_set ( "America/New_York" );

Is there some additional code I can put in place to make sure the correct time is always ascertained?

I need the $hourmin variable to always return a combination of hour + minute based on 24-hour time and Eastern Time zone.

My code is as follows:


 <?php
   $name8 = file_get_contents("test/special8name.txt");
date_default_timezone_set ( "America/New_York" );
$gethour = date("H");
$getminutes = $gettimedate["minutes"];
$gettimedate = date();
$hourmin = $gethour . $getminutes;
$currentday = date("l", time());
$currentdate = date("M j, Y");
if ($hourmin < 1500 && $currentday <> "Saturday" && $currentday <> "Sunday") {
   echo "<span class=\"namesred\">$name8 </span>";
}
  else if ( $hourmin > 1500 && $hourmin < 2300 && $currentday <> "Saturday" && $currentday <> "Sunday") {
   echo "<span class=\"namesblue\">$name8 </span>";
  }
  else if ( $currentday == "Saturday" or $currentday == "Sunday") {
   echo "<span class=\"namesblue\">$name8 </span>";
  }
?>

What are the differences and implications of UTC time and Zulu time?
  

<?php
function getArr(string $time):array
{
    $dateTime = new \DateTime($time);
    return [
        'time'=>$time,
        'timestamp'=> $dateTime->getTimestamp(),
        'dateTime' => $dateTime
    ];
}
$arr = getArr('2020-08-05');  
$arr_z = getArr('2020-08-05T00:00:00Z');  

print_r($arr);
print_r($arr_z);

echo('equal timestamps: '.($arr['timestamp'] === $arr['timestamp']?'true':'false'));

 

Array
(
    [time] => 2020-08-05
    [timestamp] => 1596585600
    [dateTime] => DateTime Object
        (
            [date] => 2020-08-05 00:00:00.000000
            [timezone_type] => 3
            [timezone] => UTC
        )

)
Array
(
    [time] => 2020-08-05T00:00:00Z
    [timestamp] => 1596585600
    [dateTime] => DateTime Object
        (
            [date] => 2020-08-05 00:00:00.000000
            [timezone_type] => 2
            [timezone] => Z
        )

)
equal timestamps: true

 

I am having a problem with PHP displaying the correct date and time. It updates as it should, but is fast by 4min and is always displaying a date in 2004. I ran a basic php script to make sure the application im using itself is not wrong. go to lunenburgledger.com/time.php

Anybody had any ideas on where to check? The system time on the Windows Server 2003 is correct. The only thing I can think of is that it was converted to a virtual machine on vmware esxi, but the system time stayed right. Any ideas?

Thanks!

OK So I've got a datepicker that sends a date in d/m/y format. My DB stores the data in Unix Timestamp Which I can convert the date to with strtotime however this does the exact date & time.

All I want is the actual day. I've spent hours trying to convert this with just the day with mixed results...

Thanks.

I am making a time clock, and I was wondering what is the best way to calculate the number of hours an employee worked?

I have a table called "statuses" it holds names of punch types:
- id = the auto_inc
- status = "in/out/break/lunch" text statuses
- paid = whether or not the punch is paid or not (true/false)

I have another table called "logging" This table holds the information about the punch type:
- id = the auto_inc
- owner = the member id
- ip = members ip
- inout = the punch type from the statuses table
- location = the city/state of where the punch took place
- date = the time the member punched

Maybe I am over thinking this, but what is the best way to calculate the hours a person has worked?

Right now I am getting all the punches for for a particular member between a date range. then loop through the data to display it and passing it to a method in a class called Calc. I want to then add the times from punch in to punch out, then the next punch in to punch out.

Any suggestions?

I have this:

    $sql = mysqli_query($conn, "SELECT ip
                                     , page
                                     , CASE WHEN referrer = ''
                                            THEN 'N/A'
                                            ELSE referrer
                                       END as referrer     
                                     , DATE_FORMAT(date, '%m/%d/%y') as date
                                     , TIME_FORMAT(time, '%T') as time
                                FROM tblTraffic 
                                ORDER BY date DESC, time DESC");

most of my traffic report contains the correct times, my time, which is CST in the USA.  but some records are off by a lot.  Does the time() function capture the time of the actual location from which the visitor is coming from?  if so, what could I do to return my timezone for any visitor?  w3 schools and php.net don't mention this.

Hi,

The hosting provider for my domain confirm me that the server time is in EST (UTC-5). They also sent me a grab supporting that
Code: [Select]
server time is now:
----------------------
Sun Nov 7 02:20:01 EST 2010
-------------------

But when I use the following code, the output I get is has 1 hr difference (UTC-6)
echo date("d M, Y h:i:s A",time());

Output==> 07 Nov, 2010 01:20:01 AM

But it suppose to give the same time as the server, ryt? Can anybody please explain?

Thanks,
