How do I display date and time for multiple time zones? I am webmaster at http://www.archerpoint.com. We would like to display our events in both Eastern and Pacific time. I only know how to control the system time zone or let the user set their own time zone, but I do not know how to display a single time entry as two separate time zones without hacking code or creating and displaying two separate entries, one for each time zone. Is there a simple solution for this?
Try to save date-time values in UTC format and while displaying them you can use format_date function 

where you will need to pass timezone value to its parameter.
