System time drift.
This is a common occurrence among specific NTP servers.
Use 'iburst' option. It helps making more reliable synchronization and initial accuracy with the server.
From 1.8.1 and later, If the default settings are not specified, the settings will automatically change to iburst=true and association-type=pool. The old NTP configurations, which have the default settings, will be updated to new default settings after the upgrade.. This change is relatively secure and is not likely to result in any problems.
