hacer hora

Short answer

In Lima, "hacer hora" means to kill time until something starts. The register is coloquial — fine among friends, out of place in a job interview or anything written to an institution. The standard Spanish equivalent is "matar el tiempo". In use: Estoy haciendo hora para mi clase.
