Edit report at https://bugs.php.net/bug.php?id=79692&edit=1 ID: 79692 Updated by: derick@php.net Reported by: eric at ericstern dot com Summary: Creating DateTime from unixtime should support fractional seconds -Status: Open +Status: Closed Type: Feature/Change Request Package: Date/time related Operating System: All PHP Version: 7.4.7 -Assigned To: +Assigned To: derick Block user comment: N Private report: N New Comment: Thank you for your bug report. This issue has already been fixed in the latest released version of PHP, which you can download at http://www.php.net/downloads.php Support for this was added in PHP 8.0: https://3v4l.org/96qtZ Previous Comments: ------------------------------------------------------------------------ [2020-06-12 00:29:17] eric at ericstern dot com > A unix timestamp by definition does not allow fractions: > > the number of **seconds** that have elapsed since the Unix epoch This in no way conflicts with that definition - it states nothing about the number being an integer, and numerous sources exist showing fractional timestamps (notably including the Wikipedia entry on unixtime). It does conflict with several touch points in PHP, though, and I'm certainly not advocating for e.g. modifying the return type of time(). Regardless, I appreciate this being left open and updated to a change request! I missed that option when opening the issue. ------------------------------------------------------------------------ [2020-06-11 23:47:13] peehaa@php.net A unix timestamp by definition does not allow fractions: > the number of **seconds** that have elapsed since the Unix epoch ------------------------------------------------------------------------ [2020-06-11 22:52:33] eric at ericstern dot com Description: ------------ PHP has supported fractional seconds apparently dating back to 5.2.2 - a bit over 13 years. However when trying to create a new DateTime or DateTimeImmutable object from a unix timestamp (via "@1591858149"), non-integer timestamps are not parsed and can throw an exception: Exception: DateTime::__construct(): Failed to parse time string (@1591858149.085) at Since new DateTime() will have a fractional component set based on the system clock, and other constructor formats support it (example: https://www.php.net/manual/en/class.datetime.php#118608), this inconsistency seems specific to unix timestamps and should be resolved Test script: --------------- https://3v4l.org/54J1b <?php $timestamp = 1591858149.085; $dt = new DateTime("@$timestamp"); $dti = new DateTimeImmutable("@$timestamp"); Expected result: ---------------- No errors; created objects correctly store the microseconds component from the timestamp. Actual result: -------------- Exception was thrown. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79692&edit=1
