cron binary package in openKylin Huanghe V3.0 amd64

 The cron daemon is a background process that runs particular programs at
 particular times (for example, every minute, day, week, or month), as
 specified in a crontab. By default, users may also create crontabs of
 their own so that processes are run on their behalf.
 .
 Output from the commands is usually mailed to the system administrator
 (or to the user in question); you should probably install a mail system
 as well so that you can receive these messages.
 .
 This cron package does not provide any system maintenance tasks. Basic
 periodic maintenance tasks are provided by other packages, such
 as checksecurity.
