Detect if system clock changed?
<p>i was wondering if i could have any help in creating a system.</p>

<p>i am looking at the idea of a java project that detects when the computer clock has been changed. The idea is to record the date and time on the computer clock and store it in a file. i then want to be able to run rules on it that shows a message if the clock has been changed. i am also looking at incorporating rules such as </p>

<p>" Allowing no more than 5 minute changes" this is to allow conveinience of changing the time by the odd minute.</p>

<p>i also need to incorprate the changes that the clock makes e.g ( going forward an hour or back an hour at certain times of the Year (Britsh Time))</p>

<p>i am not sure if there is already a java system that does this that i could look at but i literarly dont no where to start with this.</p>

<p>Any help would be greatly appreciated.</p>

<p>Thanks
Dave</p>
