Last year ... or whenever in recent times, the normal formula was changed for when the 2 yearly Time Changes take place here in the USA. At that time, I disabled the option in my Windows XP on this computer and on my Windows 98SE on my other computer. I did that because I assumed that that formula / data for when the Time Changes occur, was in Windows. I figured it was now out of date and would no longer work correctly on future Time Changes. It never occurred to me that if that formula / data IS in Windows, it CAN and probably WAS immediately already updated way back then via a Windows Update.

Is THAT the case? IS the Time Changes formula / data in Windows?
If so, HAS it been updated?
Is it correct now and I can Enable that Automatic Time Change Setting back up?

Or is that Time Changes formula / data in BIOS and no longer valid if my computer is like almost 10 years old?

it's not a formula...it's a "date range" the computer knows to change the time on the second sunday in march and the first sunday in november. this is done in windows. the BIOS clock doesn't actually care about real time or dst or anything. it's counting "clicks" from the system clock that's on the motherboard.

you seem to be describing older systems. have you run windows update on either of them? have you updated the 98 machine with the DST patch?

Date Range ... Okay, yeah, I knew that's how it was done. I just wasn't sure if it was in Windows or in BIOS or ROM somewhere. And my main concern is that that RANGE was changed last year. So, the Date Range that existed for the longest time here in the USA ... was obviously no longer the same after the change.

So, let's cut to the chase.
This computer, my old HP Pavilion 6730 with Windows XP SP3 does have ALL the Windows Updates. I have it set to automatically download them whenever they come up. And they get subsequently installed upon me initiating the computer Shutdown sequence for that night. So, if my Windows XP computer has ALL of the Windows Updates / Patches ... is it set up with the correct Date Range for the Time Changes?

My Windows 98SE Gateway computer ... Ehhh, it's just my backup computer. I pretty much don't use it. That one doesn't have ANY of the Windows Updates. I stopped messing with installing any of the Updates on that one a long time ago. That's because with all its quirks, glitches and problems that would pop up here and there, I used to do frequent Windows Reinstalls. And well, since I have Dial Up, that made for some HUGE additional downloads. So, I just stopped installing those Windows 98SE Updates.
