Answer 1

Your coordinator is likely not running in a loop, but rather submitting every 'missed' job since the start date you specified. Set the start date to the current day (e.g. 2019-06-03T00:00Z) and relaunch your coordinator.
If the start time is before 01:00, you should see a single job be launched for the day.
You may want to pass this in as a variable. Here is the call to date that will provide the current date & time in the correct format.
date -u "+%Y-%m-%dT%H:%MZ"
