The QC Services dashboards and reports default to the user's local browser time zone.
Changing the time zone updates timestamp labels but does not alter the displayed data. For relative time filters (e.g., past 24 hours), no action is needed. For absolute time filters (e.g., March 7-9, 2025), set the time zone before applying filters or reapply the filters after changing the time zone to ensure the correct data is shown. Likewise, set the time zone before zooming in on a graph.
