Bing Maps TimeZone Convert is returning an incorrect time zone abbreviation.

Question

Bing Maps TimeZone Convert is returning an incorrect time zone abbreviation.

Tim Salmon 30

When posting the following URL into a browser, I would expect the convertedTime field timeZoneDisplayAbbr to contain the three letter abbreviation "GMT" however, it contains the three letter abbreviation "IST" which could be either "Indian Standard Time" or "Irish Standard Time".

https://dev.virtualearth.net/REST/v1/TimeZone/Convert/?datetime=2022-02-05T13:38:36Z&desttz=Europe/London&key={bing maps key}.

Am I using this feature incorrectly? Or is there a problem with the TimeZone service?

Hi @Tim Salmon Greetings! I have tested the same API from Postman as well as Edge and Chrome browsers. I got the correct results for the desttz Europe/London and america/Los_Angeles. Please find the following output from Postman for the request https://dev.virtualearth.net/REST/v1/TimeZone/Convert/?datetime=2022-02-07T19:00:00Z&desttz=Europe/London&key=

Here is the output from Edge browser

Could you please test the API again by clearing the browser cookies and cache and let us know if you expereince the same behavior. Also, please try testing the API with different browsers and let us know your observations. If you notice the behavior to be consistent across the browsers, I appreciate it if you can try invoking the API from the Postman and verify the output.

Please note that it is the "Converted" timeZoneDisplayAbbr field that is manifesting the problem, not the abbreviation. timeZoneDisplayAbbr shows the three letter code IST, rather than GMT. Also, who or what is "Postman"?

Additionally, if I post the following url into a browser :- https://dev.virtualearth.net/REST/v1/TimeZone/Convert/?datetime=2022-04-07T19:00:00Z&desttz=Europe/London&key={bing maps key} For a later date, I get the converted timeZoneDisplayAbbr "GMT" rather than the correct "BST", the london daylight saving abbreviation.

Hi @Tim Salmon Thank you for the clarification. I was looking at the "abbreviation" parameter and missed the "timezonedisplayabbr" field. This looks like a bug that needs to be addressed. Let me check with the team and get back to you with more updates. Please stay tuned! Postman is a tool for testing REST API's. But never mind, as the results are consistent.

Hi @Tim Salmon ,

The issue comes from GMT actually having a one to many mapping in our dataset and, oddly, IST was the first result returned. A fix is in the pipeline for release right now but as the release portal runs many tests then deploys regionally I can't give you an exact time for the fix to reach final deployment but we expect it to be live by the end of the week.

Sincerely, IoTGirl
