RFC 3339 how make a dateTime from

Question

I'm trying to format a date passed from a google plus Api thats like the guide says in RFC 3339 format:

PUBLISHED-> datetime-> The time at which this activity was initially published. Formatted as an RFC 3339 timestamp.

So by php documentation i found that:

DATE_RFC3339 Same as DATE_ATOM (since PHP 5.1.3)

And that both format are something like:

"Y-m-d\TH:i:sP"

Actually the output of the Google api is something like:

2014-01-22T10:36:00.222Z

When I'm trying to launch command like:

$date = DateTime::createFromFormat("Y-m-d\TH:i:sP", $activity['published']); //$activity['published'] contain the  date

I have always FALSE as return. In my opinion the problem is in the final part

.222Z

any suggestion will be appreciate before cutting it by some rudimental approach...

Answer 1

There is a trick. A special constant DATE_RFC3339 was made to help, but it does not work if the last character is "Z" - which is perfectly fine for rfc3339 format. Actually JSON would specify format like that:

expected format YYYY-MM-DDThh:mm:ssZ or YYYY-MM-DDThh:mm:ss+hh:mm

But using this DATE_RFC3339 you can receive an Error message from PHP:

InvalidArgumentException: The timezone could not be found in the database

That is why we need to specify format manually:

With DateTime

$date = DateTime::createFromFormat ('Y-m-d\TH:i:s.u\Z', $time);

With Carbon:

\Carbon\Carbon::createFromFormat('Y-m-d\TH:i:s.u\Z', $time);
