PHP - Date / Time Difference

For some reason when I echo $diff and $time_remaining it ALWAYS echos with values of 3 and 7 and not sure why.

Code: [Select]
$lock_date = $row['lock_date'];
                    $current_time = time();
                   
                    // Find out if user is locked out of their account
                    if (($lock_date != "0000-00-00 00:00:00") && strtotime($lock_date) < $current_time) {
                       
                        $lock_date = strtotime($lock_date);
                        $diff = $current_time - $lock_date;                       
                        $diff = floor($diff/6000);

                        // Take minutes and perform tasks
                        if ($diff <= 10) {
                           
                            // Calculate time remaining
                            $time_remaining = 10 - $diff;

                            // Account locked error
                            $errors = true;
                            $message = "Account is locked! Must wait " .$time_remaining." minutes to log in again!";
                           
                            $output = array('errorsExist' => $errors, 'message' => $message);
                           
                        } else {
                           
                            // Clear the lock
                            $query = "UPDATE users_logins_attempts SET lockDate = NULL, ip_address = NULL, failed_logins = 0 WHERE users_id = '".$users_id."'";
                            $result = mysqli_query($dbc,$query);
                           
                            // Account locked error
                            $errors = true;
                            $message = "Account is unlocked. You may now try to log in again!";
                           
                            $output = array('errorsExist' => $errors, 'message' => $message);
                           
                        }
                       
                    }

Hi,

Trying to figure out a way to get a time difference between two times assuming they are in order..

For example; in the array below the days is easy.. because the time happens later, however nights it becomes a little more confusing.

The method I'm using now is;

if the dates are in order just stick a reference date on there, and get a difference. If they seem to be reversed, I stick a reference date on the first one and a reference date +1 days on the second and get the difference.

Can you all think of a better way?

I will use the assumption that the times will NEVER be more than 24 hrs apart..

 

Array
(
    [2] => Array
        (
            [days] => Array
                (
                    [0] => 07:00:00
                    [1] => 15:45:00
                )

            [nights] => Array
                (
                    [0] => 15:30:00
                    [1] => 02:15:00
                )

        )

 

hello, im trying to figure out the difference between 2 numbers in minutes.  here is what i have:

Code: [Select]
$tsignin="09-05 10:30:00";
$tsignina="09-06 11:30:00";

$log_in_time_stringsa = strtotime($tsignin);
$log_out_time_stringsa = strtotime($tsignina);
$difference_in_secondssa = ($log_out_time_stringsa - $log_in_time_stringsa);
$tsigna = ($difference_in_secondssa / 60);
 
  $tsigna2 = number_format(round($tsigna));
the 09-05 is sept 5, and 09-06 is sept 6.

this works if the month and date are not included.  any ideas for me so i can figure out the total difference between date/times?

I have two textboxes that inputted time, and I want to get the difference between two time.

for example:

$IN = 13:35;
$OUT = 17:35;

$OTHours = ($OUT - $IN);

$OTHours = 4.00;


and it is correct, but I have a scenario like this:

$IN = 21:35;
$OUT = 05:35;

$OTHours = -16.00;

it should be 8.00.

Any help is highly appreciated.

Thank you..

What is difference between php date(); and mysql NOW() and what should be used in script?

In php date I have 13:00h, and from MySql have 17:00h. Current date on my comp is 19:00h.

So time difference in php is +6 hours, and in mysql is +2 hours. How to synchronize this dates for users???

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.

i want to take difference of

$duedate and $returndate

and store it to another variable 

checks that variable for number of days in it

 

Hi.

Need some help on one simple task yet so hard. I have puzzled on this for days and no luck. I have a great script i got from somewhere.

Code: [Select]
function get_time_difference( $start, $end )
{
    $uts['start']      =    strtotime( $start );
    $uts['end']        =    strtotime( $end );
    if( $uts['start']!==-1 && $uts['end']!==-1 )
    {
        if( $uts['end'] >= $uts['start'] )
        {
            $diff    =    $uts['end'] - $uts['start'];
            if( $days=intval((floor($diff/86400))) )
                $diff = $diff % 86400;
            if( $hours=intval((floor($diff/3600))) )
                $diff = $diff % 3600;
            if( $minutes=intval((floor($diff/60))) )
                $diff = $diff % 60;
            $diff    =    intval( $diff );           
            return( array('days'=>$days, 'hours'=>$hours, 'minutes'=>$minutes, 'seconds'=>$diff) );
        }
        else
        {
            trigger_error( "Ending date/time is earlier than the start date/time", E_USER_WARNING );
        }
    }
    else
    {
        trigger_error( "Invalid date/time data detected", E_USER_WARNING );
    }
    return( false );
}
Now the other part is that i have 3 textboxes and i woul like to add the first one like 15:00:00 the second one 18:30:00 and the third would display the difference in
lets say seconds. At least the function displays the results in seconds. But the problem is how to get the textbox to work whitout posting the info but to use onchange

Any ideas?
Code: [Select]
<input type="text" value="" name="start_time"/>
<input type="text" value="" name="end_time"/>
<input type="text" value="______" name="difference"/>

I have date stored in database in any of the given forms 2020-06-01, 2020-05-01 or 2019-04-01

I want to compare the old date with current date 2020-06-14

And the result should be in days.

Any help please?

PS: I want to do it on php side. but if its possible to do on database side (I am using myslq) please share both ways🙂

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.

What is the best way to insert this time stamp into mysql?  This is the info I want...

Example:  Sunday, 28.1.11, 9:56

How would I also select time from the database using mysql?

I have a field set as datetime and want to compare that field to see if it is older then ten minutes. Can anyone help I am having a brain fart?

Hi!

The below dropdown will show dates/times every 15 minutes from 12am to 11:45pm for only 1 day.
I want it to show for 5 days, anyway I can do this?

Below code:

Code: [Select]
$start = strtotime('12:00am');
$end = strtotime('11:45pm');

echo '<select name="time">';
for ($i = $start; $i <= $end; $i += 900)
{
echo '<option>' . date('F j, Y, \a\t g:i a', $i);
}
echo '</select>';

Thanks for any help.
