Convert UTC/GMT or any time zone to local time in PHP· 1 minute read
Wrangling dates and times can be a somewhat arduous task for all programmers. One very common requirement is to convert a time from one time zone to another.
For this example let us assume we have a UTC date and time string (2011-04-27 02:45) that we would like to convert to ACST (Australian Central Standard Time).
<?php $utc_date = DateTime::createFromFormat( 'Y-m-d G:i', '2011-04-27 02:45', new DateTimeZone('UTC') ); $acst_date = clone $utc_date; // we don't want PHP's default pass object by reference here $acst_date->setTimeZone(new DateTimeZone('Australia/Yancowinna')); echo 'UTC: ' . $utc_date->format('Y-m-d g:i A'); // UTC: 2011-04-27 2:45 AM echo 'ACST: ' . $acst_date->format('Y-m-d g:i A'); // ACST: 2011-04-27 12:15 PM
After some experimentation between time zones that do and do not currently have DST (Day Light Savings Time) I have discovered that this will take DST into account.
Anyway a very simple tip for moving dates around in PHP.
