Our company operates off Market Hours - mainly in EST. The Tableau Server environment does not display timezones when it relates to date/time - specifically schedules. As an administrator, when I create a Schedule, it's important to have the timezone displayed so users know what date/time it's scheduled to run (and can adjust accordingly).
Example: I am testing Tableau 8 (e-mail notifications). I subscribed to a report to be delivered to me at 6:00am. I received the e-mail at 3am the next day. I was confused for a moment and realized the server is based on EST, but being located in Phoenix, I assumed I would receive the e-mail at the time displayed.
I'm sure there are other examples of how this can be an issue. Adding the designation PST, CT, MST to append to the date/time in areas would be quite helpful.
