HPE Servers with Windows Server: Offset in the System Time After Restart

2022-07-29 · Posted in Windows Server 2016/2019, Железо

One of my remote customers came across an interesting problem after a time zone change on HPE DL/ML Gen9 servers running Windows Server 2008 R2 / 2012 R2. As it turned out, when changing a system time or a time zone on HP ProLiant Gen9 servers (and on one of HP ProLiant DL580 Gen8 servers), system time was not saved and was reset to the previous one after the restart. The problem occurred on the servers, on which Windows Server booted in the Legacy mode (with native UEFI boot, there weren’t any time change problems).

The following event appeared in the system log:

As a solution of this problem, HP suggests to update ROM version to at least 1.5. This is the version of ROM-Based Setup Utility (RBSU) that has no time reset bug.

Or as a workaround solution, you can set that BIOS provides Windows the UTC system time (instead of the local time).

To do it, as we have already told above, you must create a parameter DWORD with the name RealTimeIsUniversal and the value 1 in the registry key:
HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation.

In 32-bit Windows versions, you need to create QWORD-type parameter instead of DWORD ones:

In 64-bit Windows versions, you need to create QWORD-type parameter instead of DWORD ones:
