An alik was a unit of time measurement used by the Orions.

In 2155, an Orion in the Orion Syndicate gave Captain Jonathan Archer, Commander Shran, Lieutenant Malcolm Reed and their team of MACOs one alik before they would use lethal force against them in their efforts to arrest them for breaking Orion Syndicate Economic Protocols. (ENT novel: The Good That Men Do)

Judging by the events, an alik is rather less than a minute.
