Cron creation diversity question

LFCS
#1

Hi,

Due to diverse thinking and an interest in doing things differently, could someone please kindly take a look at the screenshot and advise if the first two highlights are different from the third one? I presume they should all perform the same function.

Please advise.

Strictly speaking, in kube cron syntax 7 is not valid for day. The documentation says 0-6
The most correct in my mind of the three due to less typing is #3
#1 and #2 are semantically equal if 7 is accepted for Sunday.

#3

Appreciate Feedback. Thanks
