更新日志
| 版本 | 说明 |
|---|---|
| 8.1.0 | The behaviour with double existing hours (during the fall-back DST transition) changed. Previously PHP would pick the second occurrence (after the DST transition), instead of the first occurrence (before DST transition). |
| 7.1.0 | The microsecond parameter was added. |
示例
示例 #1 DateTimeImmutable::setTime() example
面向对象风格
<?php
$date = new DateTimeImmutable('2001-01-01');
$newDate = $date->setTime(14, 55);
echo $newDate->format('Y-m-d H:i:s') . "\n";
$newDate = $date->setTime(14, 55, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";
?>以上示例的输出类似于：
2001-01-01 14:55:00 2001-01-01 14:55:24
示例 #2 Values exceeding ranges are added to their parent values
<?php
$date = new DateTimeImmutable('2001-01-01');
$newDate = $date->setTime(14, 55, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";
$newDate = $date->setTime(14, 55, 65);
echo $newDate->format('Y-m-d H:i:s') . "\n";

echo $newDate->format('Y-m-d H:i:s') . "\n";
$newDate = $date->setTime(25, 55, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";
