How to display Date/Time fields in a timezone different than user's timezone?

I know that servicenow stores all date and times in UTC and displays them on the forms considering user's timezone.

Is there a way to display date and time fields in a timezone different than the one of the logged in user?

The reason behind my question is that the user (agent) may be located in a different timezone compared to the customer he is supporting (hurray outsourcing) and he will always have to recalculate times manually (e.g. estimated arrival time etc) from his timezone to the   customer's timezone when communicating this to the customer which may result in mistakes. So the idea is to display such times in customer's location timezone.

Any help is appreciated.

Thanks.
