取得unix时间戳
date +%s

linux:
将时间戳1123495443 换算成可以识别的年月日分秒

date -d '1970-01-01 UTC 1123495443 seconds'
FreeBSD:

date -j -f "%Y%m%d " `date +%Y%m%d` "+ %s"
#date指令源日期格式　　要转换出的格式

--------------------------------------------

获取前n分钟的时间:

[root@cpgw01 ~]# date '+%Y-%m-%d %H:%M:%S'
2007-05-16 01:17:43
[root@cpgw01 ~]# date '+%s'
1179245868
[root@cpgw01 ~]# echo 1179245794 - 60 |bc
1179245734
[root@cpgw01 ~]# date -d "1970-01-01 UTC 1179245734 seconds" '+%Y-%m-%d %H:%M:%S'
