Setting the Date and Time
The library date, time, time zone, and daylight saving time settings can be modified any time after the initial configuration.
You can modify the date and time settings manually or configure the Network Time Protocol (NTP) feature. NTP allows you to synchronize the library date and time with other components in your IT infrastructure.
If NTP is enabled, the IP address of at least one NTP server must be configured. Contact your network administrator for NTP server IP address information.

NOTE: This operation should not be performed concurrently by multiple administrative users logged in from different locations. You can access the appropriate screens, but you cannot apply changes while another administrative user is performing the same operation.
|
Users with administrative privileges can modify the date and time, but users with user privileges cannot.
- From the Setup menu, select Date & Time.
The Setup - Date & Time screen appears. The current date and time settings appear in the Current Settings Column.
- Set the date and time by doing one of the following:
- To manually configure the date and time, verify that Use NTP is disabled. Select a date from the drop-down calendar. Type the hour and minutes in the Enter Time text boxes. The library uses the 24-hour clock.
-
 |
NOTE: The Select Date drop-down list also functions as a text box, where you can type in a new date in the DD-MMM-YYYY format, for example, 05-May-2007.
|
- To use the NTP feature, enable Use NTP. Enter a valid NTP server IP address in the Primary NTP Address text box. Optionally, enter a second valid NTP server IP address in the Alternate NTP Address text box.
 |
NOTE: IP addresses may be entered using the IPv4 dot notation or using the IPv6 format. IPv4 addresses must be entered in dot notation (for example, 192.168.0.1). IPv4 address text boxes do not allow values exceeding 255 for dot-separated values.
|
- Set the time zone by doing one of the following:
- To set a standard time zone, disable Use Custom Time Zone and select your time zone from the drop-down list.
- To set a custom time zone, enable Use Custom Time Zone and set a Universal Coordinated Time (UTC) offset. The offset can be set to an accuracy of one minute. Generally, you should not need to set a custom time zone, unless your time zone does not appear on the standard list, or you want more control over your time zone setting.
- Set daylight saving time by doing one of the following:
- If you set a standard time zone, the library automatically adjusts for daylight saving time. There is no need to manually reset the clock for time changes.
- If you set a custom time zone, the library does not automatically adjust for daylight saving time. You must enable the Use Custom Daylight Saving Time setting. Once enabled, you can set start and stop times to an accuracy of one minute.
- Click Apply.
The Progress Window appears. The Progress Window contains information on the action, elapsed time, and status of the requested operation. Do one of the following:
- If Success appears in the Progress Window, the date and time were successfully set. Click Close to close the Progress Window. If NTP is enabled, the system clock synchronization may take several minutes.
- If Failure appears in the Progress Window, the date and time were not set. Follow the instructions listed in the Progress Window to resolve any issues that occurred during the operation
