问题描述
使用 minutes:seconds.tenth
进行操作时,如何计算时差?
例如,如何实现此示例: 40:24.5-67:52.4 = -27:27.9
How can I calculate time difference when operating with minutes:seconds.tenth
?
For example how can I achieve this example: 40:24.5 - 67:52.4 = -27:27.9
我本打算使用它,但后来发现十分之一:
I was going to use this but then discovered lack of tenths:
$time1 = new date('40:24.5');
$time2 = new date('67:52.4');
$interval = $time1->diff($time2);
echo $interval->format('%R%%i:%s:??');
推荐答案
就像您已经尝试过"一样,您可以使用 DateTime
扩展名:
Like you already "tried", you can use DateTime
extension:
function time_difference($t1, $t2) {
$t1 = DateTime::createFromFormat('i:s.u', $t1, new DateTimezone('UTC'));
$t2 = DateTime::createFromFormat('i:s.u', $t2, new DateTimezone('UTC'));
$diff = $t2->diff($t1);
$u = $t2->format('u') - $t1->format('u');
if ($u < 0) {
$diff = $t2->modify('-1 second')->diff($t1);
$u = 1000000 - abs($u);
}
$u = rtrim(sprintf('%06d', $u), '0') ?: '0';
return $diff->format('%R%I:%S.') . $u;
}
使用示例:
echo time_difference('40:24.5', '67:52.4');
# -27:27.9
