datetime - php: setting a timezone by UTC offset

Question

Using javascript I know that my users timezone is UTC +3.

Now I want to create DateTime object with this knowledge:

$usersNow = new DateTime('now', new DateTimeZone("+3"));

I receive as a respsonse:

'Unknown or bad timezone (+2)'

What am I doing wrong? How can I fix?

Answer 1

how about this...

$original = new DateTime("now", new DateTimeZone('UTC'));
$timezoneName = timezone_name_from_abbr("", 3*3600, false);
$modified = $original->setTimezone(new DateTimezone($timezoneName));
