Add Another Clock with a Different Time Zone

[kris84]

click the box as highlighted in above screenshot

My problem is, I don't have that option in the dialog box that appears. My only options there are for Layout Format, Date Format, and Time Format. No options for the Time Zone as in your dialog box. Changing the Time and Date Settings changes both clocks. Is there is a setting or option somewhere else that needs changed/enabled to allow this option to show up??
