Hey All,

I'm having trouble with time synchronization issues with some of my dual-boot Macs.  It's not the normal UTC/Localtime issue that affects booting between Windows and OS X.  It seems that the time often drifts just enough to break network logins (Active Directory).

So, what I want to do is write a script that runs under OS X and simply runs the commands:

systemsetup -setusingnetworktime off
systemsetup -setusingnetworktime on

when any network interface (wireless or wired) changes state to up.

We're running Leopard.  What's the best way to approach this?

Oops...I should clarify:

"when any network interface (wireless or wired) changes state to up **and has obtained an IP address**."

Hi, how much drift we talking about?  You could just write a cron job that will do the 2 commands you want to do every 5 mins or so.
