5.1.1 Time Lag

Time lag occurs when the time on the NSA falls behind the time on the time server. This may

happen if:

New Time (hh:mm:ss) This field displays the last updated time from the time server or the last

time configured manually.

When you set Date Time Setup to Manual, enter the new time in this field

and then click Apply.

Get from Time Server Select this to have the NSA get the time and date from the time server you

select in the Time Server Address field.

Time Server Address Select a time server from the drop-down list box. Check with your ISP/

network administrator if you are unsure of this information.

Synchronize Now Click this button for the NSA to retrieve the correct time from the

configured time server right away.

Time Zone Choose the NSA’s time zone.

Enable Daylight Saving Daylight saving is a period from late spring to early fall when many

countries set their clocks ahead of normal local time by one hour to gain

more daytime light in the evening.

Select this option if you use Daylight Saving Time.

Start Date Configure the day and time when Daylight Saving Time starts if you

selected Enable Daylight Saving. The hour field uses the 24 hour

format. Here are a couple of examples:

Daylight Saving Time starts in most parts of the United States on the

second Sunday of March. Each time zone in the United States starts

using Daylight Saving Time at 2 A.M. local time. So in the United States

you would use March, [Second Sunday], at 2:00.

Daylight Saving Time starts in the European Union on the last Sunday of

March. All of the time zones in the European Union start using Daylight

Saving Time at the same moment (1 A.M. GMT or UTC). So in the

European Union you would select March, [Last Sunday]. The time you

specify depends on your time zone. In Germany for instance, you would

enter 2 AM because Germany's time zone is one hour ahead of GMT or

UTC (GMT+1).

End Date Configure the day and time when Daylight Saving Time ends if you

selected Enable Daylight Saving. The o'clock field uses the 24 hour

format. Here are a couple of examples:

Daylight Saving Time ends in the United States on the first Sunday of

November. Each time zone in the United States stops using Daylight

Saving Time at 2 A.M. local time. So in the United States you would select

November, First, Sunday, at 2:00.

Daylight Saving Time ends in the European Union on the last Sunday of

October. All of the time zones in the European Union stop using Daylight

Saving Time at the same moment (1 A.M. GMT or UTC). So in the

European Union you would select October, Last, Sunday. The time you

specify depends on your time zone. In Germany for instance, you would

type 2 because Germany's time zone is one hour ahead of GMT or UTC

(GMT+1).

Offset Specify by how many hours to change the time for Daylight Saving Time.

Apply Click this to save your changes.

Cancel Click this to discard changes.
