首先频率有问题：
https://developers.weixin.qq.com/blogdetail?action=get_post_info&docid=00006e5976cf9866f726a217b51800&highline=video%7C%26%E7%BB%84%E4%BB%B6%7C%26%E7%9A%84%7C%26bindtimeupdate&token=905838030&lang=zh_CN
但是精度有问题，模拟器上出来是是浮点数，设备上（iOS，Android）都是整数：
代码如下：
onStartPlay () { this.startWallClcokInSec = new Date().getTime() / 1000 this.lastVideoTimeInSec = 0.0},onTimeUpdate (e) { var currentWallClockInSec = new Date().getTime() / 1000 var currentVideoTimeInSec = e.mp.detail.currentTime var wallClock = currentWallClockInSec - this.startWallClcokInSec console.log(`wallclock:${(wallClock).toFixed(3)}, videoTime: ${(currentVideoTimeInSec).toFixed(3)}`)} |
模拟器输出：
wallclock:1.247, videoTime: 1.098wallclock:1.747, videoTime: 1.598wallclock:1.997, videoTime: 1.848wallclock:2.248, videoTime: 2.098wallclock:2.747, videoTime: 2.598wallclock:3.247, videoTime: 3.098wallclock:3.747, videoTime: 3.598wallclock:3.997, videoTime: 3.848 |
iOS输出：
wallclock:0.232, videoTime: 0.000wallclock:0.234, videoTime: 0.000wallclock:1.235, videoTime: 1.000wallclock:2.251, videoTime: 2.000wallclock:3.237, videoTime: 3.000wallclock:4.241, videoTime: 4.000wallclock:4.875, videoTime: 4.000 |
bindtimeupdate参数：（貌似进来只是个整数？）
JSON.stringify(e, null, 2)："{ "mp": { "type": "timeupdate", "target": { "dataset": { "eventid": "0" }, "id": "", "offsetTop": 0, "offsetLeft": 0 }, "currentTarget": { "dataset": { "eventid": "0" }, "id": "", "offsetTop": 0, "offsetLeft": 0 }, "timeStamp": 78938, "detail": { "currentTime": 4, "duration": 4.63 } }, "type": "timeupdate", "timeStamp": 78938, "target": { "dataset": { "eventid": "0" }, "id": "", "offsetTop": 0, "offsetLeft": 0, "currentTime": 4, "duration": 4.63 }, "currentTarget": { "dataset": { "eventid": "0" }, "id": "", "offsetTop": 0, "offsetLeft": 0 } }" |
设备信息：

谁来解释下，怎么获取毫秒级的时间。
