time keeps changing in bios

#1 Post by retired » Fri Oct 20, 2017 3:00 pm

Hi - I've got a t-60 running xp and linux - everything works fine but the time kept jumping ahead 4 hours - so I went into the bios and set the time to where it should be -that worked for a short time - so then I set the bios time to 4 hours earlier than it should be and after awhile it reset itself to 4 hours ahead of what it should be - no matter what I do it always goes back to 4 hours ahead - I have xp and linux set to the correct time zone. ???

A near-dead CMOS battery comes to mind.
Available on e.g. eBay, check for: lenovo t60 cmos

All TP's use the same CMOS battery. If you have another machine laying around, that is another possibility.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

Windows assumes that the system time is local time, while Linux assumes that system time is GMT, and adds the time zone offset. I'm pretty sure this is the cause.

You ahould be able to set either Linux or XP to not change the CMOS settings. Linux will likely be tge easier to change but IDK.

There's a registry key in Windows 7 that forces it to accept system time as UTC. Unfortunately, Windows XP does not support this registry key. :(
