[SOLVED] server time adjustment

[Grant Holmes]

I have a processing form reporting the time when a record is inserted. This field is never changed. However, our server (Yahoo) is in London. My client is in CA. I'd like to post a time relevant to LA.

 

In my page I do:

 

$time=date("Y-m-d H:i:s");

 

Is there a way to subtract the 9 hour difference? H-9??

Timezone --- --- 
e Timezone identifier (added in PHP 5.1.0) Examples: UTC, GMT, Atlantic/Azores 
I (capital i) Whether or not the date is in daylight saving time 1 if Daylight Saving Time, 0 otherwise. 
O Difference to Greenwich time (GMT) in hours Example: +0200 
P Difference to Greenwich time (GMT) with colon between hours and minutes (added in PHP 5.1.3) Example: +02:00 
T Timezone abbreviation Examples: EST, MDT ... 
Z Timezone offset in seconds. The offset for timezones west of UTC is always negative, and for those east of UTC is always positive. -43200 through 50400

Try that

If you want the date() function to return dates/times in CA timezone, use this at the beginning of your script:

date_ default_ timezone_ set('America/Los_Angeles');

 

As far as making a script show dates auto-adjusted to the client's timezone, it's a little trickier. The only way to get the client's timezone is with javascript.

Thanks for the help gang.

 

phpSensei, I read that page, but I'm noob to PHP and have no idea what to edit/add/whatever.

 

rhodesa, (see above on being a newbie)... I put that above my code within the php like this:

date_ default_ timezone_ set('America/Los_Angeles');
$time=date("Y-m-d H:i:s");

but then the page failed to display. HELP!?

[rhodesa]

sorry...i copied/pasted the function name and it ended up with spaces in there:

 

date_default_timezone_set('America/Los_Angeles');
$time=date("Y-m-d H:i:s T");

 

I also added a T to your date format so you could see what timezone it was using

[Grant Holmes]

rhodesa,

 

I need to leave the T off, as I store this value in my table and the field isn't set for that, so would leaving it off still work?

[rhodesa]

of course...i just added it in for debug purposes...so you could confirm which TZ it was using

[phpSensei]

<?php
      $timezone = "America/Los_Angeles";

putenv('TZ=$timezone');
echo date('M j Y, H:m:s');
?>

[Grant Holmes]

phpSensei, your solution returns zeros: "0000-00-00 00:00:00" and I don't see where you're assigning the value to: $time

 

rhodesa, yours still returns a blank page.

putenv('TZ=$timezone');

 

 

try

 

<?php
      $timezone = "America/Los_Angeles";

putenv('TZ=$timezone');
echo date('Y-m-d h:i:s');
?>

 

returns: 2008-02-07 03:31:12

[rhodesa]

I assume on mine, you put in an echo?

 

<?php
  date_default_timezone_set('America/Los_Angeles');
  $time=date("Y-m-d H:i:s");
  echo "In CA it is currently ".$time;
?>

 

[phpSensei]

<?php
putenv('TZ=America/Los_Angeles');
echo date('Y-m-d h:i:s');
?>

 

Okay this works: 2008-02-07 12:31:56
