Solaris 11 global zone timezone

Am new on Solaris

If I compare with ESXi default timezone is UTC and we have to set BIOS timezone to UTC too .

What we follow and best practice in Solaris Sparc servers .

Thanks in advance .

Are you saying that your sparc Solaris 11 global zone sits on EXSi, and then you have zones inside that?

I'm not clear what you are asking. Do you want UTC for Sol 11? Or not?

The Best practice is to have the service processor/mainboard clock configured to use UTC. Depending on the hardware, that might be the only choice and the internal clock itself always run in UTC anyway.

There is no recommendation for the OS default timezone on the global or non global zones, just set the one that best suit your needs. Setting the timezone doesn't change what the clock contains but how its content is displayed.
