A time zone is a region on the earth that has a uniform standard time, usually referred to as the local time. Local time is the UTC time plus the current time zone offset for the considered location. Some time zones also have an offset called DST added during the summer period. The DST offset is typically +1 hour.
Consistent date and timestamping across a network is critical for system wide access control, security, communications, scheduling, alarms, and events. Network time uses the NTP protocol that provides the correct current UTC time.

In WorkStation, all times are by default displayed in local time. This means that a time, independent of its source, is displayed in the same time zone as the operating system on which WorkStation is installed. By configuring the operating system time and time zone settings, you configure how times are displayed in WorkStation. For more information, please refer to the manufacturer’s manual for the operating system.

The Enterprise Server time and date settings are configured through the operating system settings on which the Enterprise Server is installed. The time zone offset, configured through the Enterprise Server, is added by Building Operation to the UTC time. The Enterprise Server time zone settings are therefore independent of the operating system time zone settings.
