You can change the timezone on the CLI
check the current timezone with command
show timezone
Then, very important, check the string for your time zone, e.g. if you are in Melbourne Australia (which has daylight savings) then check the list with command
show timezones
once you see your timezone in the list, you can go ahead and configure it.
configure terminal
clock timezone Australia/Melbourne
follow the prompts. You will need to restart ISE.
And apply the same config on all of the nodes in your deployment.
