If timezone is UTC -*, (such as UTC/GMT -5 hours), then the date in all Protection Console's reports related to activities is one day behind the date when the activity happened.
If activity reports are scheduled, they also arrive with an incorrect date which is one day behind the real date.
Issue in the product.
The behavior is observed when the viewer's machine has a negative timezone offset (like GMT-5). Due to grouping requirements, the backend returns the "date" field with a pre-applied timezone offset.
The UI applies timezone offset (-5 hours) one extra time and the user sees the previous day. This issue affects not just the Activity list, but also Active Alerts list and Alerts history.
This issue has been fixed in Acronis Cyber Protect Cloud 20.09.
