What does the Time Zone field in User Preferences / User Information affect?
When the Time Zone field in User Preferences / User Information is changed some -- but not all -- timestamps in ITNCM will be displayed in that timezone.
Note that after changing Time Zone you must restart the ITNCM GUI for the change to come into effect.
The screenshot below shows which timestamps will be affected by this preference:
The items highlighted in green will be displayed in the User Preferences Time Zone, but the item highlighted in red (a timestamp in the UOW log) will not change as it is a part of a string generated by a Worker Server rather than a singular field.
