If the client data contains data of the type DateTime then, upon receiving the data from the client, Microsoft Dynamics NAV Server converts this data into UTC based on the client time zone. When passing data of type DateTime back to the client, Microsoft Dynamics NAV Server converts the time back to the local time zone of the client before presenting the data to the end user.

Different countries and regions sometimes have different rules for determining when and if to start and end Daylight Saving Time. If computers running Microsoft Dynamics NAV Server computers are kept current with Windows updates, then changes to Daylight Saving Time are managed automatically.

Microsoft Dynamics NAV Server cannot determine the time zone of origin for a Web service. Therefore, all Web server communication should be in UTC. All business logic is executed with respect to UTC.
