Complex schedule is wrongly executed

[claas-fridtjof-lisowski]

We have this schedule:

0 10 10,27 * */2,*/3,*/4,*/5

Expected behaviour

Expected trigger schema in words:

“At 10:00 on day-of-month 10 and 27 if it's on every 2nd day-of-week, every 3rd day-of-week, every 4th day-of-week, and every 5th day-of-week.”

From https://crontab.guru/#0_10_10,27__/2,/3,/4,*/5

Actual behaviour

it triggers as soon as the day of week matches.

We use Kubernetes 1.17, which seems to use v1.1.0 for the CronJob controller.

The Kubernetes CronJobs are triggering the jobs as described in the expected behaviour: 2x month only on a weekday and not on a Monday and only on day 10 and 27 of the month is the cron triggered.

In Argo v2.11.7 robfig/cron/v3 is used.

Here though the "actual behaviour" is observed and the day of month is ignored.

Is that v3 behaviour the "correct" one or is this a bug? Or is there an alternative for our schedule?
