your time zone and Greenwich Mean Time (GMT).
Daylight Savings
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 give 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
Daylight Savings
. The
o'clock
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 first
Sunday of April. 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 select
First
,
Sunday
,
April
and type 2 in the
o'clock
field.
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
Last
,
Sunday
,
March
. The time you type in the
o'clock
field 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).

NBG334W to send.
An alert is a type of log that warrants more serious attention. They include system errors,
attacks (access control) and attempted access to blocked web sites or web sites with restricted
web features such as cookies, active X and so on. Some categories such as
System Errors
consist of both logs and alerts. You may differentiate them by their color in the

Alerts are e-mailed as soon as they happen. Logs may be e-mailed as soon as the log is full
(see
Log Schedule
). Selecting many alert and/or log categories (especially
Access Control
)
may result in many e-mails being sent.
