I'm not seeing the problem you are trying to demonstrate. Is there some reason why you believe the timestamp on a file that you changed on September 14th should have a timestamp that is somehow related to the current hardware or software clock?

I wanted to know which should be the best way to sync time for a linux machine. We have an application server and a database server, both using RHEL 5.8 as the OS.

/* calculate the sunrise time for Lisbon, Portugal
Latitude: 38.4 North
Longitude: 9 West
Zenith ~= 90
