The Dell Unity XT system stores all schedule times in Coordinated Universal Time (UTC). The Time Zone setting in Unisphere is purely for display purposes, translating the UTC time to the selected local time for the administrator. When the time zone is changed, it does not alter the underlying UTC time at which existing schedules are set to run. Therefore, a schedule created at 8 PM in a previous time zone will continue to run at that same absolute UTC time, which will be displayed as a different local time in the new time zone.

A. This statement is unclearly worded and does not accurately describe the system's behavior with UTC-based scheduling.

B. The system time (UTC) is likely correct; the issue is the user's expectation of how a display time zone change affects pre-existing schedules.

D. A restart of the management server is not required for a time zone setting change to be applied for display purposes.

Dell Unity Family Unisphere Administration Guide (Version 5.3)

"Date and Time" section (Page 288): "The system time is set to Coordinated Universal Time (UTC) and cannot be changed. You can

however

select a time zone for displaying the time in Unisphere." This confirms schedules are based on a fixed UTC time

and the setting only affects the display.
