Using the shell to turn the time string and time stamp to each other

date +%s can get Unix timestamp;
use the shell to turn the time string with the timestamp:
date-d "2010-10-18 00:00:00" +%s output shape: 1287331200
and the time stamp is converted to a string to do this:
date-d @1287331200 "+%y-%m-%d" output shape such as: 2010-10-18
If you need to get the days before and after the specified date, you can:
1, seconds= ' date-d "2010-10-18 00:00:00" +%s ' #得到时间戳
2. seconds_new= ' expr $seconds + 86400 ' #加上一天的秒数86400
3, date_new= ' date-d @ $seconds _new "+%y-%m-%d" ' #获得指定日前加上一天的日前
