If you try to read time zones from left to right, you may end up getting confused. Why? Because the time zone represented in the leftmost column may display a time later than the current time. For example, if you display Seattle time (Pacific Time) as your current time zone and Dublin time (Coordinated Universal Time, also known as Greenwich Mean Time) as your alternate time zone, you'll need to remember that Dublin time is eight hours later than Seattle time, even though you see it first if you're reading from left to right across the row.
Swap Time Zones You can use the Swap Time Zones button in the Change Time Zones dialog box when you go somewhere. With Swap Time Zones, you can quickly switch between the time for the place you are visiting and your home time. For example, if you travel to Dublin, switch to that time zone to make it easier to schedule meetings and to show up to those meetings at the right time. When you return home, click the Swap Time Zones button to switch back.
You may be wondering how Outlook handles meeting requests across time zones. Here's how: Time for items in the Outlook Calendar is stored based on Coordinated Universal Time (UTC). That is, when you book something in your calendar in Outlook, you book it in a fixed point in time. If you are in one time zone and you send a meeting request to an attendee in a different time zone, the meeting item is displayed at different local times on each person's calendar but at the same absolute time in UTC.
