Time lag occurs when the time on the NSA falls behind the time on the time server. This may happen if:
• the time server is no longer reachable
• if the NSA is shut down often (the NSA internal battery keeps time when the NSA is shut down and this may cause possible variance)
• power surges occur.
The NSA gives no warning if time lag occurs. You should resynchronize the time after a power surge or after you have shut down the NSA several times.

Saving Daylight saving is a period from late spring to fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening.
Select this option to manually enter Daylight Saving Time settings. Clear this option to have the NSA automatically retrieve Daylight Saving Time settings from the Internet. The NSA will download a new daylight saving resource file from the Internet every month.
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 type 2 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).
