I took a look at /etc/init.d/hwclockfirst.sh and it is similar to what I am doing. The problem with a cron job is that it would run every 5 minutes, or whatever I set it to, and it would run then... when cron is running. Sometimes I change to a cron-free runlevel so that heavy tasks don't get slowed down by swapping (remember, my system is a cron-operated alarmclock, and what makes it that is thrashing on cron jobs). I'm not sure about adding another cron job to my tiny crontab of one line. I also only want the system time to change whenever it is over 5 minutes off of the more accurate hardware clock. > 2.

I tried ntpdate about a week ago. I looked up a number of time-servers, and I couldn't connect to any of them. The way it looks from my end is that if the proxy isn't specifically configured to handle one type of traffic, that type of traffic gets dropped. Its rather annoying really, ports have been opened to allow some people to play games over the internet, or to use stuff like KaZaa, but nothing to let me get the time. > 3.

I know what is on my side of the proxy (7 systems, 6 of which are windoze). No time-server. Mostly people playing M$ games over the network, and using stuff like KaZaa. > 4.

A slightly higher priority is their webmail interface. I can't even login to it with my favoured browsers. I can type in my username and my password, but it is impossible for me to push the login button. I hate it when people require the use of a GUI browser. > Just some thoughts... HTH.
