Using the new UIM 20.4 CU1, the operator console dates are again showing the wrong regional locale format.
This issue was used to be in the UIM 20.3.3 which was enhanced in order to display the date format accordingly to the browser regional locale format.
Release : UIM 20.4 CU1
Component : UNIFIED INFRASTRUCTURE MGMT
This issue will be fixed as part of the upcoming Cumulative patch release (UIM 20.4 CU2)
