  No impact to end users, Cloudera Manager Console will be unavailable during the maitenance window

* maintenance plan and timeline (link to a wiki or etherpad is fine)
 1 - Copy correct TZ file to system configuration
 # cp /usr/share/zoneinfo/UTC /etc/localtime
 2 - Set ZONE variable to correct TZ
 # echo 'ZONE="UTC"' > /etc/sysconfig/clock
 3 - Verify TZ has changed
 # date
 4 - Verify CM is functional and has no errors

* rollback plan / rollback point (at which point will you determine to roll back)
 
 1 - Set TZ back to before changes
 # cp /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
 # echo 'ZONE="America/Los_Angeles"' > /etc/sysconfig/clock
 
* notification mechanisms:
  Is email at the beginning and end of the window ok?
  
* who will be point, who else will be involved
