I would write simple script that will report time to server (UDP  
packets, files or something else). The server will check reports  
every N minutes or seconds. Every time when server notices incorrect  
report, it would raise an alarm ("red bulb on the wall").

In windows environment, workstations may have scheduled task to put  
current date-time to specific file on fileserver (say, samba). Simple  
shell script will check age and correctness of these files (compare  
mtime and their content). This simple system should work OK if you  
require precision of two seconds.
