All, I have a question about setting the system time at bootup. Network connectivity is through a Bluetooth access point, and I would like to use an init script to set the system time using the rdate command. Is there a better way? Also, while rdate works, the system time is set to PST, but I'm on the East coast, so would like the time to be EST. How can I change the default timezone on the Gumstix? Any help is appreciated.

That has your timezone info, the offset from GMT (UTC), and the daylight savings time zone. For setting the date, I use ntpdate, which is quite simple. Depending on the accuracy you require, you might want to enable ntpd in the buildroot. Phil |

I use ntpdate too, and have it run when the interface comes up by altering the relevant interface in /etc/network/interfaces to add: up sleep 10;ntpdate pool.ntp.org under the interface definition. The "sleep" is there because when the interface comes up, it isn't immediately actually ready to send/ receive traffic over TCP/IP apparently. If you remove the sleep, ntpdate complains about not being able to find the host. C |

Thanks for the suggestions Philip and Craig. In the end, I changed the timezone as suggested, and created an init script to call rdate after a slight delay to allow the network interface to come up. I used rdate since the version of the kernel on the Gumstix doesn't have ntpdate, but in the future, I'll just edit /etc/network/interfaces to use ntpdate.

ntp is in the buildroot -- just add it as a TARGET in the top-level Makefile, and it'll get built and installed, including the ntpdate command.
