Change a Date to a Different date based on timezone..

[lynxus]

Hi Guys..

 

How can I change a date on the fly ?

Everything is UTC on my server.

 

How can I change a date to something else on the fly?

 

Ie:

 

$timezone = "cet";

$datetime = "2011-09-04 19:53:00";

 

echo $datetime($timezone);

 

So I can give it a datetime and have it echo the datetime as if it were in the other timezone?

 

Thanks

Graham

strtotime

I did think of " date_default_timezone_set('America/Los_Angeles');"

 

However, Does this now change the timezone of the script?

I dont want this.

 

i want the script to stay in UTC however I want to be able to echo a date through a function that turns the inputted date into whateever datetime i ask for ?

 

( im not sure how strtotime will fix this issue? Can I punt a timezone to it?

What method are you using to find the time zone?

[lynxus]

None currently ( Im assuming the data is correct in the DB )

 

I get dates from the database ( thats saved as UTC )

 

Id like to convert some dates on the fly to other timezones ( so i can display datetimes in other peoples locales ) 

 

I hope that makes sense?

Handling timezone conversion with PHP DateTime

<?php	
$myDateTime = new DateTime('2011-09-04 23:05', new DateTimeZone('GMT'));
$myDateTime->setTimezone(new DateTimeZone('America/New_York'));
echo $myDateTime->format('Y-m-d H:i');
?>

Combination of the ‘select’ and ‘function’ will enable you to select ‘time zone’. Then you can manipulate the above code.

Is there a list of what can be put into this field:

 

$myDateTime->setTimezone(new DateTimeZone('America/New_York'));

 

I cant seem to find a definitive one

Sorry for being an undertaker, but I dont think my question needs a new topic.

 

So, does this function includes the 'daylight saving time' thing?

[xyph]

It should, for those timezones that have DST.
