Set Time in PHP?

[lynlimz]

Hi,

My server and where I reside are in different timezones.

How do I set it to be the same as my timezone?
Like adding +10 or something to the time?

How do I go about it?

thanks

//Set offset to be the numbe rof hours ahead you want
$offset = "10";
$adj_time = date("g:i:s a", mktime(date("H")+$offset,date("i"),date("s")));
//$adj_time will contain the new time
print $adj_time;

Hi,

Thanks for helping.

I was also wondering..how do I set the offset for dates?
Since my offset between the server and my timezone is +15, how do i make the dates reflect too?

this is my script version. thanks

<?php
$last_modified = filemtime("$SCRIPT_FILENAME"); print(date("d/m/y", $last_modified));
?>

[freddydoesphp]

This will show the date reflected by the offset, is that what you are after?
$offset = "15";
$adj_time = date("g:i:s m/d/y", mktime(date("H")+$offset,date("i"),date("s"), date("m"), date("d"), date("y")));

Wow, that's quite cool. Mind if I make use of it?

[freddydoesphp]

Actually since one interested me more than normal so I came up with a little function to return a new date and time based on an offset that you set as a parameter. If there are better ways of doing this please someone chime ine, I am alwasy looking for improvement. But here goes:
function adj_timezone($meth, $hour) {
if ($meth == "+") {
$adj_time = date("g:i:s a | m/d/y", mktime(date("H")+ $hour,date("i"),date("s"), date("m"), date("d"), date("y")));
$time = explode("|", $adj_time);
}
elseif($meth == "-") {
$adj_time = date("g:i:s a | m/d/y", mktime(date("H")- $hour,date("i"),date("s"), date("m"), date("d"), date("y")));
$time = explode("|", $adj_time);
}
else {
$time = "";
}
return $time;
}


//Sample Usage: to go back timezones
$time = adj_timezone("-", 10);
//Or to move forward
$time = adj_timezone("+", 10);

//Function returns an array the first element holds the new time the second the new date
$newtime = $time[0];
$newday = $time[1];
print $newtime."<br>";
print $newday."<br>";

Hi,

I'm getting the time and date fom when a file was last modified. So how do i set the offset for it? Using your functions?

thanks for your help..=))

[freddydoesphp]

<?
function adj_timezone($meth, $hour, $moddate) {
$hour = ($hour * 3600);
if ($meth == "+") {
$newtime = $moddate + $hour;
}
elseif($meth == "-") {
$newtime = $moddate - $hour;
}
else {
$time = "";
}
$adj_time = DATE("m-d-y | g:i:s a", $newtime);
$time = explode("|", $adj_time);
return $time;
}

$moddate = filemtime("./iplister.php");

//To move forward three params(-/+, number of hours, filemtime
$time = adj_timezone("+", 10, $moddate);

//Function returns an array the first element holds the new time the second the new date
$newtime = $time[0];
$newday = $time[1];
print $newtime."<br>";
print $newday."<br>";

?>

You could also do it this way:

<?
$offset = '10'; #hours
$offset_time = time() + ($offset * 3600); #3600 seconds in one hour
$readable_offset_time = date("g:i A",$offset_time);

echo $readable_offset_time;
?>

$offset can be changed to - or + numbers.

[freddydoesphp]

Yeah but what if you wanted to use it more than once on your page, you would have to write that code every time, why not make a function out of it, and then you can call on the function with one line of code whenever you need it?

[jrap]

True. Here is a function for the code

<?
function time_offset($offset)
{
	$offset_time = time() + ($offset * 3600); #3600 seconds in one hour
	$readable_offset_time[0] = date("g:i A",$offset_time);
	$readable_offset_time[1] = date("F d, Y g:i A",$offset_time);
	return $readable_offset_time;
} 

$time = time_offset('-24');
echo $time[1]; #for date and time
echo $time[0]; #for just time
?>

*edit*
included function to display date also if wanted.

Okay, well what if they want to subtract hours, your function doesn't allow for that, furthermore the one I posted above allows for this and returns a nice array with the date and the time. Though they pretty much do the same thing

[jrap]

not to get in an argument about who's function is better , but the one I wrote can actually subtract time if the offset is negative.

I used freddy's very first tiny little function and used "-4" and it worked like a charm...

[freddydoesphp]

I don't want to argue about something so silly either, but what the guy was looking for who started the post was a way to take the value of filemtime() and add 10 hours to it, so that is what I gave hime, yours is good, but it isn't what he was after.

[lynlimz]

Hi Guys,

Thanks for your help.
But Hey, there ain't a need to quarrel. Both functions are good in their own ways and I'm keeping both for reference.
robp's would be good for just displaying the time yah? =)

Anyhow,
I'm using freddydoesphp's as it allows more configurations and allow me to set the file last modified too.

Thnaks for your help.
