Subject Re: [Replication] Using time offsets instead of absolute time
Date Tue, 20 Jan 2009 12:24:22 GMT
IMO, NTP is the way to go. Time synchronizing servers when doing
replication is a part of the deal. Any other solution is a bit
overworkilling, when kikking some sysadmin's bottom could do the job
more efficiently ;)
