Kibana version:
7.9.3
Elasticsearch version:
7.9.3
Original install method (e.g. download page, yum, from source, etc.):
on Prem
Describe the bug:
User has set up an alert that should always fire.
But the re notifying is not consitent and also the alert has been marked as resolved but there was no resolution.

Steps to reproduce:
- Create an index threshold Kibana alert that always is true
- Set the notify config
- Check the results, e.g. in .kibana-events-log
The timing is not correct. Sometimes it takes longer than 1h to get re notified
Expected behavior:
The Re notify happens every hour at the same time
Screenshots (if relevant):
