时代比较bsd/MacOSX [英] epoch time comparison bsd / MacOSX

问题描述

这对除了我以外的所有人来说都是显而易见的，

This should be obvious to all but me,

我有一个充满纪元时间戳的文件，我正在尝试获取最近7天的记录.

I have a file full of epoch timestamps and I'm trying to get the records from the last 7 days.

因此我在Mac中尝试了此操作:

So I tried this in my mac:

PAST=$(gdate -d "7 days ago" +%s)
if [ $timeval -gt  $PAST ]; then
  do stuff 
 fi

示例错误输出:

TS from data, Human fr data, TS from $PAST, Human from $PAST

推荐答案

文件中的时间戳以毫秒为单位，而不是秒.将它们除以1000.

The timestamps in your file are in milliseconds, not seconds. Divide them by 1000.
