setting time and date

I am sorry if this is a redundant question. I have searched the forums and tried to fix it with some suggestions that I have read but I cannot get this to work.

I am running debian sid. I am also dual booting with winxp. I wll try to lay out the problem clearly.

1. I start out in debian. My clocks were set fine until daylight savings occurs. So I had to adjust them since they didn't automatically. I changed it with the date command. "date mmddhhss" and it was fine.

2. I then went to the bios and it too was not changed. So I adjusted it in the bios.

3. booted into windows to play a game a couple days later and the hours were way off, about 5 hours. changed the time in windows.

4. when i went back to linux the hours were again off.

I have set the timezone to be Canada/EST, tried setting the time with "date", and then running hwclock --localtime --systohc, but that is not solving the problem.

any ideas?

the date command using the complex format for date in "man date" (the man page).

date [MMDDhhmm[[CC]YY][.ss]]

like i set mine by doing date 110701082003

that means: Nov. 11 01:08(am implied) 2003

seconds default to 00

if the time is 1pm, date 110713082003 1pm = 13

Your Linux probably is treating the hardware (BIOS) clock as if it were set to GMT (Greenwich, England Mean Time). If that is the case, you need to tell your Linux to not do that.

If you have Mandrake 9.X, the tool you would use would be the Mandrake Control Center. Then, in the Mandrake Control Center date and time settings, you would select your time zone, at which time it will ask you if you want to make your BIOS clock be GMT, to which you would reply no.

I'm not certain about Linux distributions other than Mandrake, but suspect that the procedure would be similar.

if you're connected to the internet you can also use ntp to sync your system's time with that of a ntp server.

That's bizarre. I run debian sid (funnily enough it's also dual-booted with XP) and I experienced that exact same problem. I seemed to go completely spastic for a while and could be off by several hours (not necessarily a nice round number either) over the course of a day. I thought my hardware clock had packed it in but if you had that problem too. I think it might have something to do with the date package in that case. Mine hadn't changed due to daylight saving so I had to change it manually. I think that's when all the toule started. I'd pretty much given up on it but your post made me look at the time again and it was EXACTLY one hour behind. It seemed to have stabilised. I changed it to the right time from the BIOS this time and I'll keep you posted on how accurate it stays.
