Some example json files display a wrong timezone

For the following example https://github.com/Azure/azure-rest-api-specs/blob/master/specification/azsadmin/resource-manager/update/Microsoft.Update.Admin/preview/2016-05-01/examples/UpdateRuns/Get.json#L24, if you search the keywords "utc", you will find that there are lots of key named "startTimeUtc" or "endTimeUtc", but the time is actually in time zone UTC-8.

You can find more examples like this with following query on github:

1. https://github.com/Azure/azure-rest-api-specs/search?q=lastUpdateTimeUtc&unscoped_q=lastUpdateTimeUtc
2. https://github.com/Azure/azure-rest-api-specs/search?q=startTimeUtc&unscoped_q=startTimeUtc
