Setting Time/Date in linux??

[skyy]

Hi..

I am working on Arm-linux os on developement board. The OS reset the time and date whenever the board is reset. Is there any way that i can run a script to set the time/date instead of manually setting it?

Thanks..

Provided the board has network access, you may want to get NTP set up and running. Otherwise you will need to keep power to the device even when it is off.

I proposed two solutions, which one are you trying to figure out?

means that your battery on the M/B is out of date, instead of finding other solutions you should update your battery asasp

/usr/sbin/ntpdate -v 130.133.1.10 131.188.3.220 193.67.79.202 ; /sbin/hwclock --systohc > /dev/null 2>&1

hi.. thanks for the reply..

But i cant find the ntpdate function anywhere. Instead i got this "rdate" function which is part of busybox. Any idea how to use it?

Check out the rdate man page.

I think ntp.org keeps a listing of servers. You could try searching their list for one that is close to you geographically, or you could just use pool.ntp.org.

Hi thanks for the link...

But when i try with pool.ntp.org, "rdate" return with an error: Host name lookup failure.

I tried other time server also gives me the same error.
Any idea?

Sounds like you don't have internet access. Can you ping google from the device?
