Bug #81569 [Opn->Nab]: Relative time with decimal value

Edit report at https://bugs.php.net/bug.php?id=81569&edit=1 ID: 81569 Updated by: requinix@php.net Reported by: tm8544 at hotmail dot com Summary: Relative time with decimal value -Status: Open +Status: Not a bug Type: Bug Package: Date/time related Operating System: Windows 10 x64 PHP Version: 8.1.0RC5 Block user comment: N Private report: N New Comment: You aren't seeing the full picture with just the date portion. https://3v4l.org/gMsML As with other miscellaneous inputs that don't have meaning to the parser, the decimal point acts as a separator, so "+1.5 year" means "+1" and then "5 year". "+1" is a tzcorrection. https://www.php.net/manual/en/datetime.formats.time.php "5 year" is a relative amount. https://www.php.net/manual/en/datetime.formats.relative.php The result is +1 or -1 hour for the timezone correction and 5 years added to the date. Previous Comments: ------------------------------------------------------------------------ [2021-10-30 10:25:40] tm8544 at hotmail dot com Description: ------------ In PHP Manual ›Supported Date and Time Formats ›Relative Formats number format is [+-]?[0-9]+ , no decimal point included. If number is given with decimal value, number should be cut before decimal point, eg "+1.5" should be read as "+1" Now, it is read as "5" Test script: --------------- <?php // in examples below, this script was run at 30.10.2021 echo date("j.n.Y", strtotime("+1.5 year", time())); echo date("j.n.Y", strtotime("-1.5 year", time())); ?> Expected result: ---------------- 30.10.2022 // 1 year ahead 30.10.2020 // 1 year backwards Actual result: -------------- 30.10.2026 // This is 5 years ahead, not 1.5 years ahead 30.10.2026 // This is 5 years ahead, not 1.5 years backwards ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81569&edit=1
