Question

What format is this date time in PHP 2012-08-16T21:14:03.447?
How can I convert it to Timestamp and vice versa?

I have a timestamp format 1345108443790, how to get the Date time ?

For the people who downvoted/close request this question:

I was getting weird result when trying to convert 1345108443790 (I got this value from third-party website) to DateTime, but after many attempts and @Truth’s suggestion got to know that after trimming last 3 digits (may be microseconds?) and then passing it in function actually solved it and is giving the right result. Something to learn here, one click downvoters!

Answer 1

This is similar to ISO 8601 (Timezone is missing though), a.k.a. the standard for date/time stamps.

Use strtotime() it parses it correctly. You may want to consider DateTime objects as well.

Working example:

$ts = strtotime("2012-08-16T21:14:03.447");
echo date("H:i:s Y-m-d", $ts);
