DateTime weekday issue in PHP

Question

I am using the following:

$endtime = new DateTime(date('r', '1329717600'));
$endtime->setTimezone(new DateTimeZone('America/Los_Angeles'));
echo $endtime->format('w - l');

It should be outputting "1 - Monday"; but it is instead outputting "0 - Sunday"...

How do I fix this?

Answer 1

That's technically correct - the time/date on that timestamp would have been Sunday 10pm in LA, Monday 6am in UTC.

Answer 2

Try the following:

$endtime = new DateTime(date('r', '1329717600'), new DateTimeZone('America/Los_Angeles'));
echo $endtime->format('w - l');

PHP documentation comment on the setTimezone function:

The timestamp value represented by the DateTime object is not modified when you set the timezone using this method. Only the timezone, and thus the resulting display formatting, is affected.

Answer 3

$endtime = new DateTime;
$endtime->createFromFormat('U', 1329717600, new DateTimeZone('America/Los_Angeles'));
echo $endtime->format('w - l');
