sack time

Time for sleeping

Sack time is informal for sleep or time spent sleeping.

The sack is slang for bed, so sack time is bed time—though it emphasizes duration rather than the hour of retiring: I need some sack time before the early flight.

Common in military contexts, where sleep is often scarce and therefore precious.
