Use standard time zone abbreviations when indicating a clock time in text. A resource for time zone information is timeanddate.com.
Clock times for Association events available in multiple time zones should be indicated in Eastern Time to reflect the location of the NACDD office in the Eastern Time Zone. Use the abbreviation ET, unless it’s necessary to be more specific. Event times should be arranged during normal business hours to include business hours in as many time zones as possible.
Abbreviate time zone on first reference for zones within the continental United States when linked with a clock reading. Do not separate time and zone with a comma.
Example: 3 p.m. ET or noon CST
