SRG-4400 User Manual (Iss. 06) Menu System • 5–27
The options for the Month field are: January through December.
The options for the Year field are:
• 2000 through 2034 for the Summer DST, Winter DST and Leap Second menus
• 2007 through 2034 for the UTC DateTime menu
Note these dates may already have been pre-set using the Daylight Saving and Leap Second menu
options detailed below.
Leap Second
The options in this menu line are: Off, User Defined.
If set to “User Defined”, then the time and date will automatically adjust at the time and date set
in the Leap Second Event (UTC) menu.
If the menu line “Leap Second” is set to “Auto from GPS”, the time and date of the event is
automatically determined via the GPS connection.
Action DateTime
This menu item allows the user to set or adjust the time at which a Summer DST Event, a Winter
DST Event, or a Leap Second Event occurs.
The field “hh:mm:ss:ff” is used to set the time at which the event happens. The sub-fields in the
field “hh:mm:ss:ff” represent hours: minutes: seconds: frames. Sub-fields are adjusted directly,
and automatically reflect any changes.
For these menus, only the “hours” sub-field is adjustable. A highlight cursor is displayed showing
which sub-field is active and hence editable in the field.
Note these times may already have been pre-set using the Daylight Saving and Leap Second
menu options detailed below.
Daylight Saving
The Daylight Saving mode should be selected only after setting the required Country Code. The
options in this field are:
• Off — No Daylight Saving services are provided by the SRG-4400.
• User Defined — A single spring and autumn daylight saving service is provided.
• Automatic — If the country code is set to Australia, Brazil, Canada, New Zealand, USA
or any European country, then a full daylight saving service is provided over a sequence
of years up to 2034. This option is only enabled when Country Code is set for a DST
supported country.
If set to User Defined, then the Video and LTC menu times will automatically adjust at the times
and dates set in the Summer DST Event and Winter DST Event menus. Once a spring event is
completed, the year of the programmed event is changed to 2035 so that it will never repeat. Once
the autumn event is completed, the year of the programmed event is changed to 2035 so that it
will never repeat, and the Daylight Saving mode is also set to Off. To program the next pair of
events, set the mode to User Defined, and then enter the next pair of times and dates in the
Summer DST Event and Winter DST Event menus.
When this field is set to Automatic, the Summer DST Event and Winter DST Event menus are
immediately updated to be ready for the next two events based on the current time and date, and
the previously configured Country Code.
While set to Automatic, as each DST Event occurs, it is updated to be ready for the following
year.
