Trying to add sites to tenant via API
Using addSocketSite in Postman.

Fails, reporting: {"errors":[{"message":"timezone [US/Pacific] is unknown","path":["site","addSocketSite","input","siteLocation","timezone"]}],"data":{"site":{"addSocketSite":null}}}
Inspecting the results of the lookup, I can see that UA has three timezones

When you lookup US there is only one timezone.

If I am importing 15 sites only the sites in Mountain timezone succeed.
Is this a production tool or method?
