When a user sets an item's publishing restrictions, it's possible to define dates and times in the "publishable from" and "publishable to" fields. These date/time values will be interpreted in the time zone of the server.
This is a problem for our users because a single Sitecore CM instance will have content for many country-specific sites and content authors are located across different time zones. If the server time zone is UTC, then the UK content authors might be OK, but the US content authors will have a hard time setting up the publishing date/time, especially since there is no indication as to what time zone is used.
What is a good way to solve, or at least mitigate this issue?
