Administering Global Time Zone Support

The time zone records that are shipped as seed data with Siebel Business Applications include the 74 world time zones, each with a start date of 1 January 1900. These time zones are the same time zones Microsoft uses in its operating systems. In addition, there is a time zone detail record for each of the continental United States time zones with a start date of 1 January 2007, which reflects the changes in start and end dates for daylight savings time for 2007. If the daylight savings time start and end dates change again, you add a new record for the year of the change. For more information about global time zone support, see Siebel Global Deployment Guide.

Use the Time Zone administration view to:

• Edit the text descriptions of time zones and their abbreviations.
• Manage the active status of time zones to control which time zones are available to users for use in the Siebel Business Applications.
• Manage multilingual translations to control how time zone information appears to users in multiple languages.
• Set the start and end dates for daylight savings time for different years and zones.

Tasks for administering time zones include:

• Modifying Time Zones
• Maintaining Translations of Time Zones

Modifying Time Zones

You rarely modify a time zone's regional settings. However, you might want to modify other time zone settings such as the display name or daylight savings rules, because these settings occasionally change.

NOTE:  You cannot add or delete time zones.

To modify time zone settings

1. Navigate to the Administration - Data screen, then the Time Zone Administration view.
2. In the Time Zone list, select the time zone record you want to modify.
3. Modify the fields as necessary.
4. In the Detail list, add or modify the records as necessary.

   Some fields are described in the following table.

   Field	Comments
   Name	Type the name of time zone.
   Standard Abbreviation	Type the abbreviation for the time zone.
   DST Abbreviation	Type the abbreviations for daylight savings time (DST).
   Start Date	Select the date on which the offset rule becomes effective.
   UTC Offset	Type the number of minutes for the offset from Coordinated Universal Time (UTC) when DST is not in effect.
   DST Bias	Type the number of minutes for the incremental DST offset from UTC when DST is not in effect.
   DST Start Ordinal	Select a value for the DST start ordinal. This field is part of the rule that determines when DST starts. For example, if the rule is the first Sunday in April, First is defined in this field.
   DST Start Day	Select a value for the DST start day. This field is part of the rule that determines when DST starts. For example, if the rule is the first Sunday in April, Sunday is defined in this field.
   DST Start Month	Select a value for the DST start month. This field is part of the rule that determines when DST starts. For example, if the rule is the first Sunday in April, April is defined in this field.
   DST Start Time	Type the number of minutes after midnight that DST starts. For example, if DST starts at 2:00 A.M., set the start time to 120.

Maintaining Translations of Time Zones

You maintain translations of the text-based fields for each time zone using the Time Zone Administration view.

To maintain translations of time zones

1. Navigate to the Administration - Data screen, then the Time Zone Administration view.
2. In the Time Zone list, select the time zone you want to translate.
3. In the Time Zone Translation list, create a new record, and complete the necessary fields, including the translation of the Name field for the selected language.
4. Repeat Step 3 for each language required for translation.

Date and Timestamps

The date and time used for timestamping records are obtained by the Siebel Server. When a remote user runs the Siebel client in disconnected mode, the Siebel Server runs on the user's computer and takes the date and time from that computer.

If the Global Time Zone feature is enabled, then fields of data type UTCDATETIME are converted to UTC during operations for the Siebel Application Object Manager. For more information, see Siebel Global Deployment Guide.
