If you have the EST time in the first sheet, you will want to subtract 1 hour
for sheet 2, 2 hours for sheet three, etc.

If the time is in Sheet1!A1

The formula for CST is: =Sheet1!A1-(1/24)
MST: =Sheet1!A1-(2/24)
PST: =Sheet1!A1-(3/24)

Anytime you update the meeting time in Sheet1!A1, it wil automatically
change the time in the other sheets. Be sure and format the cells to show
the date/time.
