[Bug 1545108] Re: crontab ignores the day of month, and executes based only on the time and the weekday.

[Rob]

So, I just learned that if I have a crontab with both the day of month
and day of week fields set, it will run on both the given weekday and
given the day of the month, and to have a crontab only work on a certain
day of the month, the day of week field should be set to an asterisk.

** Changed in: cron (Ubuntu)
       Status: New => Invalid

Title:
  crontab ignores the day of month, and executes based only on the time
  and the weekday.

Status in cron package in Ubuntu:
  Invalid

Bug description:
  here is my crontab:

    45   5   *     *     1-5   pkill -f flash
    48   6   *     *     1-5   musicalarm
    50   9   *     *     1-5   mpc random off
    30   7   5     2       5   echo -e "I'm not coming in today.\n\nHave a good one!" | mail -s "No pikupordropov needed" email at example.com

  Obviously I have changed the email a bit, but it gives you an idea.
  The email got sent today, even though it is clearly not the 5th of
  February. Something similar happened a couple days ago (another
  command that was scheduled for that day, but earlier in the month).
