Windows "management name" field has wrong timezone

The behavior you are experiencing, where the “management name” field in Intune Hybrid Join devices shows a timestamp that's four hours ahead of your local timezone, is a known quirk. While it doesn’t impact how everything works, it might cause some confusion about consistency and control.

The timestamp added to the management name field (like username_Windows_MM/DD/YYYY_HH:MM) isn't based on your device’s local time. Instead, it comes from the Intune backend or Azure AD registration service, which often operates in UTC or another standard time zone.

Azure AD and Intune are global services that typically log events in UTC or server local time, not your device’s local time.-

The management name is automatically generated when your device joins Hybrid or enrols in MDM, and it uses the server-side timestamp when that event took place.- You can't change

this timestamp through import settings or configuration profiles it’s a system-generated ID meant for internal tracking and ensuring uniqueness.
