Solaris time drifts when a local zone is configured with an offset of virtual zone clock from the global system clock
Last updated on OCTOBER 02, 2016
Applies to:Solaris Operating System - Version 11.3 to 11.3 [Release 11.0]
Oracle Solaris on SPARC (64-bit)
Starting with Solaris 11.3 a local zone can be configured to have its own time configuration different from the one on the global zone, through the configuration of the global-time property, which can be set to false so the local zone can change the zone-specific time.
When there is high CPU load on a local zone that has the zonecfg(1M) property global-time configured to false to have the zone-specific time, the time on the global zone can jump and if NTP is enabled it could go into maintenance state, with the following errors on the /var/adm/messages file:
Also cron jobs could fail and the cron daemon will be restarted.
This issue happens on SPARC platforms running Solaris 11.3 without SRU 12.4 or later.
