Office 365 NTP or Time Source reference documentation

Copper Contributor

Hi there, need to answer a compliance question about accurate time source for log correlation. Has Microsoft documented anything about the time servers used by Office 365 and how it maintains accuracy? I wasn't able to find anything other than changing the time zone for user end.


Our company is all in the cloud with Azure Active Directory.

I encountered the same in the past, and recalled that Microsoft provided an official document for the tenant time sync accuracy proven.

Btw, please expect Office 365 act as SaaS so that there is no time sync between but make sure both on-prem and Office 365 tenant.
