As a principle, play should be continuous, from the time the match starts (when the first service of the match is put in play) until the match finishes. These maximum times start from the moment that one point finishes until the first service is struck for the next point.

• 25 seconds: After a point ends the server has 25 seconds to start the next point.
• 90 seconds: When changing ends, players have a maximum of ninety (90) seconds to rest.

• 120 seconds: At the end of each set, players can rest a maximum of 2 minutes. 

The start time rule says "A player may not leave the court after the match has started (includes the warm-up) without the permission of her opponents. The TFIM CA reminds its members that "Leaving the court for more than 2 minutes should be very exceptional and justified."
