Steps to reproduce:

1. Use monitoring by Acronis Cyber Protect Cloud MSP by HTTP
2. Wail for items in Acronis CPC: Get devices: Acronis CPC: Device discovery
3. When your items starting to collecting data check data for acronis.cpc.device.backup.next[{*} {#NAME}

   {*}] this itmes gives you timestamp for next run of backup job

4. Trigger last(/Acronis Cyber Protect Cloud MSP by HTTP/acronis.cpc.device.backup.next{#NAME}) < now() containing small error. Default item interval is 1min but function now() is time function which is calculated every time when zabbix received data + additionally another 30s. Every time we have for 30-40s fault positive, before we have new updated data with timestamp for next run.
5. Trigger can be adjusted like this: last(/Acronis Cyber Protect Cloud MSP by HTTP/acronis.cpc.device.backup.next{#NAME}) < (now()+120)

Result:
Fail positive events in nights. Event is automatically closed after 30-40s.
Expected:
New event only when is backup not done for bigger period of time.
