java 获取整形时间戳

Question

java中有没有办法获取int型的时间戳，因为之前数据库里是设计成integer的，实体类里也是integer的，所以改起来不方便。只好用int的时间戳
而new Date().getTime()、Calendar.getInstance().getTimeInMillis()、System.currentTimeMillis()这三种获取的都是long类型的，有办法获取整型的吗？

Answer 1

Because the database was previously designed to be integer, and the entity class was also integer, so it was inconvenient to change it

It needs to be changed even if it is inconvenient. If you want to save millisecond timestamps, you must use long,intnot enough.

Answer 2

Can’t you handle it yourself?
For example

System.currentTimeMillis()/1000

Answer 3

The timestamp must be of long type. The int type cannot fit the timestamp

Answer 4

You can use shaping to convert to seconds or minutes, but the accuracy will be lost
