[Deploying Sakai] Monitoring Server clocks

Hi All,

A quick question: Do you monitor your server clocks for drift from an 
authoritative source?

The reason I ask is we had an issue on Monday where NTP had crashed on 
one node causing the server clock to drift alarmingly. This was causing, 
for instance, Turnitin submissions from that node to fail. I have 
written a little piece of code that checks the servers clock against the 
database and the remote ntp server and will generate an alert if it 
drifts more than 30s:


Any one else doing something like this?
