Milliseconds to UNIX timestamp
提问by t.vb.w
Anyone have any idea how I would go about converting a timestamp in milliseconds from 1970(from Android's System.currentTimeMillis();) to a UNIX timestamp? It need only be accurate to the day.
任何人都知道我将如何以毫秒为单位将时间戳从1970（来自 Android 的System.currentTimeMillis();）转换为 UNIX 时间戳？它只需要准确到当天。
I figure I could divide by 1000to get seconds, and then divide by 86400(number of seconds in a day) to get the # of days. But I'm not sure where to go from there.
我想我可以除以1000得到秒，然后除以86400（一天中的秒数）得到天数。但我不确定从那里去哪里。
Many thanks.
非常感谢。

Divide it by 1000
除以 1000

Dividing by 1000 is enough to get a Unix timestamp. You don't need any numbers of days or anything like that.
除以 1000 就足以获得 Unix 时间戳。你不需要任何天数或类似的东西。

long unixTime = System.currentTimeMillis() / 1000L;
