What is Resign On Time?

Resign On Time in chess does not appear to be a recognized term or phrase in the official glossary of chess terms. This term probably refers informally to a situation where a player, seeing an inevitable loss due to time constraints in timed matches or because of the positions of the pieces on the board, voluntarily surrenders before their time officially runs out. Nonetheless, for a precise definition, it is recommended to refer to established chess resources or governing bodies.
