Security intelligence update release date and time

Hello,

I noticed that release date/time on Latest security intelligence updates for Microsoft Defender Antivirus and other Microsoft antimalware - Microsoft Security Intelligence and Antimalware updates change log - Microsoft Security Intelligence isn't identical for same Security intelligence update version.

For example, on Latest security intelligence updates for Microsoft Defender Antivirus and other Microsoft antimalware - Microsoft Security Intelligence it says that current version 1.427.746.0 is released on 5/12/2025 7:12:15 AM while on Antimalware updates change log - Microsoft Security Intelligence it says released on 5/12/2025 12:56:21 AM.

I first assumed that difference is because of time zone difference, but number of hours is not rounded.

Can you please help me to understand which time is right one and why there is a difference?

Thank you!
