Clock time when the participant is in bed or lights are out from type II polysomnography
stloutp under Sleep Monitoring/Polysomnography/Sleep Architecture in SHHS variables
Conventionally, this variable would be called the start of time in bed (TIB). In Visit 1 this variable represents the number of epochs from recording start.

Clock time (hours of the day) when the participant is out of bed or lights are on from type I polysomnography
stlonp_dec under Sleep Monitoring/Polysomnography/Sleep Architecture in CCSHS variables
Conventionally, this variable would be called the end of time in bed (TIB). 24 hours were added to the original values that occurred after midnight
