Bug Crontab does not kick at the given time
I have crontab set to be triggered daily @ 8 am and 8:20 am server time.

Code:
00 08 * * * /web/scripts/check.sh
20 08 * * * /web/scripts/check.sh

Code:
uname -a
Linux mymac 3.10.0-327.36.3.el7.x86_64 #1 SMP Thu Oct 20 04:56:07 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux

Code:
ls -ltr /web/scripts/check.sh
-rwxrwxr-x 1 user1 user1 10180 Nov 10 13:41 /web/scripts/check.sh

The check.sh generates a file with the date timestamp using >> (redirection). Running the check.sh manually works fine and i see the updated timestamp.

Can you please let me know why check.sh did not get triggered all these days when i set it to trigger everyday @ 8 am and 8:20 am.
