在我的申请中,我需要把包括事件结束时间在内的一名JSON混为一谈。 当这项活动正在进行时,我需要计算完成这一审查所需的时间。 为此,我使用了这一法典:
// I get the time and convert it from millis to seconds
long end = System.currentTimeMillis() / 1000;
techsTime.add((int) (queue.event.get("event0").endtime - end));
时间过后,我改为过去。 这在像“最佳的布莱克”和“温和会希望”这样的一些装置中是一种药。 但今天,我与一位好客的兹特·布莱德一道测试了我的看法,而这次活动所留时间非常奇怪。 这个数字是负数,数字与原数字相差很大。 我用不同的价值对 app进行了测试,没有模式,他们像随机数字一样,例如:
Optimus Black -> 21m 32s
ZTE Blade -> -38m -57s
我已想到,该系统在这两种装置中可能有所不同,但两者都使用CM7作为顾问。
我认为,问题可能在于一个装置没有适当安装。 如果你抽出时间,这种区别似乎就好是一小时,这可能会造成错锁。 当你考虑确定的时间时,还要看时区。 这两种装置可能同时显示,但其中一个装置在不同的时间区配置。
现代装置不会把锁在网里,而是仍然有可能,例如ZTE。
Use System.nanotime() - it is specially created in order to measure the time between 2 events.
System.currentTimeMillis() uses the system clock which does not update every 1 millisecond and thus is unreliable and giving different results.
