Siebel Global Deployment Guide > Deploying Siebel CRM with Global Time Zone > About Global Time Zone and Universal Time Coordinated (UTC)Global deployments typically span multiple countries and have users working in several different time zones. The global time zone feature allows you to track dates and times consistently across time zones by using Universal Time Coordinated (UTC). Using UTC is strongly recommended. UTC is enabled by default for Siebel applications. CAUTION: If you do not want to deploy with UTC or are not ready to do so, then you must review Guidelines for Both UTC and Non-UTC Deployments and related topics. Also review this topic for relevant information. For information about UTC in upgrade scenarios, see Siebel Database Upgrade Guide. NOTE: UTC is essentially the equivalent of Greenwich Mean Time (GMT). However, certain localities using GMT or British Standard Time (BST) as a time zone observe daylight savings time (DST). DST does not apply for UTC itself, because it serves as a baseline against which all of the other time zone and DST offset adjustments apply. The global time zone feature allows you to store date-time data in a common format and provides the following key benefits:
NOTE: Windows regional settings on client computers do not affect UTC. Optionally, you can set the database server to UTC, although you can deploy your Siebel applications to use UTC without doing so. For more information, see Setting the Database Server to UTC. |
