Daylight Savings Time 2007 - firmware upgrade ?
In 2007 the start and end dates are going to be different for Daylight Savings Time. As a result, servers are going to need to be patched. Here is a related link I came across:
http://sunsolve.sun.com/search/document.do?assetkey=1-26-102617-1
My question is, how do I know whether or not my firmware (PROM) needs to be updated too ? I have searched and have not found a lot of information on the topic of the firmware. Does anyone have any good links or pertinent information on whether the firmware would need to be updated or not ? I have several Netra T1's, Sunfire V480's, and my Sunblade 100 workstation that I am concerned about. Here is the OBP level from one of my V480's that is on Solaris 8: OBP 4.6.8 2002/09/04
and here is the OBP from a V480 on Solaris 9: OBP 4.10.14 2003/11/19.
Thanks for any information.

Requiring firmware updates to cope with DST changes is a relatively unusual problem and specific to the servers mentioned.
None of the servers you mentioned are on the list, so you don't need to worry.
But I would probably do firmware updates on production servers just on general principles.
The netra's are old and havent had any new firmwares released for a long time, so you probably don't need to worry. But the V480's would probably be worth doing.
Firmware and OS revision are relatively unconnected.

The platforms mentioned in the Sun Alert 102617 that you linked above,
are all Sun Fire Midrange Server systems.
Their "firmware" is a part of a completely different sort of of architecture.
Their system controllers are a tiny computer, with its own OS, inside the Sun Fire system.
That Real Time Operating System (RTOS) that runs on the SC's has its own
time-of-day function that is independant of whatever Solaris gets installed
to whichever domain or domains you configure to the computer.
Thus the need for the Sun Alert, separate from any TOD discussion for Solaris..
