Events should start at the scheduled time. In order to accomplish this, the DIC must close the sale of entries. This does not mean the DIC may arbitrarily refuse to accept a late entry. However, after play has begun a director may not restart the game under any circumstances to enable a late entry to play.

The tournament chairman and the DIC should make starting time changes only in cases of emergency, since some people may arrive based on the published time, unaware of any change.

When a starting time change affects the second session of a two-session event, the DIC must announce the new time just before the first session ends, explaining the reasons for the change and asking that all players start the next session at the new time.
