বেশিরভাগ সাইটের ব্যবহারকারীর পছন্দসই টাইমজোনগুলিতে সাইটে তারিখগুলি দেখানোর জন্য কিছু উপায় প্রয়োজন। নীচে হয় দুটি তালিকা যে আমি পাওয়া যায় এবং তারপর এক পদ্ধতি ব্যবহার করে পিএইচপি তারিখসময় সালে নির্মিত পিএইচপি 5 বর্গ।
রেজিস্টারটিতে ইউটিসি থেকে অফসেট পাওয়ার চেষ্টা করার সময় এর মধ্যে কোনটি ব্যবহার করার চেষ্টা করা ভাল তা জানতে আমার সহায়তা প্রয়োজন।

অথবা কেবল পিএইচপি নিজেই ব্যবহার করছেন:
$timezones = DateTimeZone::listAbbreviations();
$cities = array();
foreach( $timezones as $key => $zones )
{
foreach( $zones as $id => $zone )
{
/**
* Only get timezones explicitely not part of "Others".
* @see http://www.php.net/manual/en/timezones.others.php
*/
if ( preg_match( '/^(America|Antartica|Arctic|Asia|Atlantic|Europe|Indian|Pacific)\//', $zone['timezone_id'] )
&& $zone['timezone_id']) {
$cities[$zone['timezone_id']][] = $key;
}
}
}
// For each city, have a comma separated list of all possible timezones for that city.
foreach( $cities as $key => $value )
$cities[$key] = join( ', ', $value);
// Only keep one city (the first and also most important) for each set of possibilities.
$cities = array_unique( $cities );
// Sort by area/city name.
ksort( $cities );
দেখে মনে হচ্ছে যে পিএইচপি রিলিজ ব্যবহারের সাথে এটি শেষ হওয়ার চেয়ে সবচেয়ে নিরাপদ হবে। শহরের নামগুলির সাথে টাইমজোনগুলি বেঁধে দেওয়ার সময় আপনি এই অ্যারের চারপাশে ফ্লিপ করতে পারেন।
