7.5.5.5
Global Tab
Global settings are for items such as the unit’s real-time clock, network time resource, remote fader timeout,
simple network management protocol, and unit status.
7.5.5.5.1 Unit Time
The time settings in the unit can be observed in this section of the tab. The Unit Time data includes the current
UTC value in the JSD-100MA real time clock, the time zone offset from UTC for standard time, the
abbreviations for standard and daylight saving time, and whether daylight saving time is observed at this
location.
7.5.5.5.2 Set Time
This date button sets the time and time zone information in the JSD-100MA.
The JSD-100MA itself only uses time of day in logging. Further, all log entries
are made in UTC. When viewed through the GUI, log data includes the time in
UTC, the time at the JSD-100MA (XSP Time), and the time at the GUI (GUI Time).
The use of these three time zones allows for simple comparison of device logs,
even when the devices are in multiple time zones. The Date and Time dialog
allows setting of date and time data for the JSD-100MA. Since the JSD-100MA
uses UTC time, the displayed time is UTC. If the system is using an NTP server,
you do not need to set the date and time. If no NTP server is available, set the
date and time to the current UTC time. The bottom portion of the dialog box deals with the date and time at
the JSD-100MA itself. Set the Time Zone field to the offset from UTC for standard time in the time zone where
the JSD-100MA is located. If daylight saving time (summer time) is observed at the JSD-100MA location, check
the corresponding checkbox. Note that this checkbox indicates whether daylight saving time is ever observed
at this location, not whether it is currently in effect. For example, you would check the checkbox in California,
but uncheck it in Arizona. Fill the next two fields with the abbreviations for standard time and daylight saving
time in the time zone where the JSD-100MA is located. The daylight saving time abbreviation will not be used
if the daylight saving time observed checkbox is unchecked, but you may want to fill it in anyway. Clicking OK
transmits the data to the JSD-100MA.
