PHP - What Are The Differences And Implications Of Utc Time And Zulu Time?

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.

PHP 5.2.6

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.

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!

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>";
  }
?>

Let's say I am buying a share for $10.

If I sell the share on the same day BEFORE 3:30PM, it will be sold for $10, but if I keep the share past 3:30PM, I want the code to automatically add $1 (Taxes and such) once in the the price of the share in database, after that no matter how many days pass by, the price will remain the same.

 

I've thought about CRON jobs, but I have no idea how to make/use them or set them up.

 

Any direction or help is appreciated.

 

 

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?

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,

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.

Hey Guys!
I have the following doubt.

When echoing from Server like this:

Code: [Select]
echo "time=" . time();
I get the time in the following raw format: 1299272294

I would really like to echo it with this format: Tue Mar 1 23:50:00 GMT-0300 2011

Is there a way I could do that?

Really looking forward for some help on this one,

Thanks a lot in advance!
Cheers!

Hey guys,
How would I go about subtracting Today from a previous day to find the difference?

For example, I want to subtract TODAY from a previous date in my database, to determine if the difference is greater than 1 day.

Any ideas? I tried doing the subraction in TIMESTAMPS, but when I convert the date back to Y-m-d H:i:s, I got some weird year and time.
 

heres is my code for time but it ddnt the time i get was not same in my computer
Code: [Select]
$date = date("y-d-m") . " at " . date("h:i:s");
                            $time = time();

Hey Guys.

I have the following problem on mysql database:

With php using $time = time(); I receive for example: 1302638294

I need something more accurate than this because sometimes I receive on my DB the same value (2 times) and it generates some conflicts due to the fact I am using this information to know which user sent some information, first, second, etc...

Does anyone have any suggestions on how I can solve this problem?
Thanks a lot in advance!
Cheers.

I want my forum to sort through the threads from youngest to oldest. How would I go about doing this? I originally used the NOW() function when inserting a new thread, but I had no clue how to make the threads sort via the date. I could use the time() function, but all users would see for the date would be numbers.

Each time someone posts, the field "lastpost" is updated to send it to the top of the forum (suppose to).

Any ideas?  - I'm just learning the ropes for time and dates with PHP.

Hi all, I am trying to figure out how to add 60 days to a mysql stored DATE, then subtract the current date from that date to see how many days there are... Its for a 60 day trial and when they signed up, it put the date in which they signed up in the database table...

Here's what I have, but it's not working... But I can't get it to add 60 days to a mysql stored DATE,... then of course I have to figure out how to do the subtraction...
Code: [Select]
$CustomerSaasDateStarted = $row['CustomerSaasDateStarted'];
$CustomerSaasDateStartedPlusSixtyDays = date("Y-m-d", strtotime($CustomerSaasDateStarted, "+60 days"));
// Test Output
echo 'Date Trial Started: '.date("M d, Y", strtotime($CustomerSaasDateStarted));
echo '<br />';
echo '60 days from Date Trial Started: '.date("M d, Y", strtotime($CustomerSaasDateStartedPlusSixtyDays));
echo '<br />';
