Sample: Retrieve time zone information

  • Article

This sample shows how to retrieve time zone information. You can download the sample from here.

Note

This sample applies to both Dynamics 365 Customer Engagement (on-premises) and Dataverse.

How to run this sample

To obtain a local copy of all samples and build them, follow these steps:

  1. Download or clone the Samples repo so that you have a local copy.
  2. (Optional) Edit the dataverse/App.config file to define a connection string specifying the instance/organization you want to connect to.
  3. Open the sample solution in Visual Studio and press F5 to run the sample. After you specify a connection string in dataverse/App.config, any sample you run will use that connection information.

If you don't specify a connection string in dataverse/App.config file, a dialog opens each time you run the sample, and you'll need to enter information about which instance or org you want to connect to and which credentials you want to use. This dialog caches previous connections so that you can choose a previously used connection.

What this sample does

The RetrieveAllTimeZonesForLocale method is intended to be used in a scenario where it uses the current locale id to retrieve all the time zones.

How this sample works

In order to simulate the scenario described in What this sample does, the sample will do the following:

Setup

Checks for the current version of the org.

Demonstrate

  1. The RetrieveCurrentUSerSettings method retrieves the current users timezone code and locale id.
  2. The RetrieveAllTimeZonesForLocale method uses the current locale id and retrieves all the time zones.
  3. The GetTimeZoneCodeByLocaleAndName method retrieves the timezone by name and locale id.
  4. The RetrieveTimeZoneById method retrieves the timezone by id.
  5. The RetrieveTimeZonesLessThan50 method retrieves time zones less than 50.
  6. The RetrieveLocalTimeFromUTCTime method retrieves the local time from UTC time.
  7. The RetrieveUTCTimeFromLocalTime method retrieves the UTC time from the locale time.

Clean up

Display an option to delete the sample data that is created in Setup. The deletion is optional in case you want to examine the entities and data created by the sample. You can manually delete the records to achieve the same result.
