php时间函数
字符串转时间
function strtotime ($time, $now = 'time()')
eg:
$t = strtotime('2017-11-18');
echo strtotime('next Sunday', $t), '<br>';//$t后的周日,自然语言,好傻逼
echo strtotime('+5hours');//当前时间5小时后
时间转字符串
function date ($format, $timestamp = null)
date('Y-m-d H:i:s');
javascript
字符串转时间
let t = new Date('2018-03-06 12:00:00')
时间转字符串
let s = (new Date).getTime()

字符串转时间long t = new Date().getTime()long t = sdf.parse("2018-03-06 12:00:00'").getTime();getTime返回1970-01-01 00:00:00起的毫秒数时间转字符串String s = sdf.format(t);
