Timing Regulation

Meet directors should incorporate one of the below timing statements into their meet information sheets in accordance with the 2019 Timing Regulations effective with the 2019 USMS Rule Book:

When using pads (automatic timing) as primary timing: 
Official times set at this meet will be eligible for ILMSA Records, USMS Top Ten, USMS National Records, and FINA World Records, except times recorded only using manual backup timing are ineligible for FINA World Records.

When using buttons (semiautomatic) as primary timing:
Because the primary timing system at this meet will be semiautomatic, Official times will be eligible for ILMSA Records and USMS Top Ten, but ineligible for USMS National Records and FINA World Records.

When using watches (manual) as primary timing:
Because the primary timing system at this meet will be manual, Official times will be eligible for ILMSA Records and USMS Top Ten, but ineligible for USMS National Records and FINA World Records.

For meets that are swum in multiple pools, the following additional information applies:
Anyone who is attempting a national record needs to be informed of the new timing regulations by the Meet Director so that person can be put in a pad-timed pool regardless of their seed time.
