Hi @anon43219174,
Just to clarify, timezones in Asana are automatically set based on your device timezone. If you’re based in the US and work on a task with a due date that was created by folks based in Europe, you will see the due time in your timezone, but this due time will remain the same.
If you’d like to see this due time in multiple timezones, I’d recommend creating a new #productfeedback so other folks can upvote and support your request! If you’d like to be able to set your due date manually make sure to support this existing #productfeedback Manually set and fix time zone;
Hope this helps to clear things up
