Clock time (hours of the day) when the participant is in bed or lights are out from type I polysomnography
stloutp_dec under Sleep Monitoring/Polysomnography/Sleep Architecture in CCSHS variables
Conventionally, this variable would be called the start of time in bed (TIB).
Average daily midpoint for rest period in main sleep in all days from actigraphy
avgrestmidpoint5 under Sleep Monitoring/Actigraphy in MESA variables
In this study, rest period (i.e. rest interval) is defined as in-bed period (i.e. time in bed).
End point time for bed (in-bed) from type I polysomnography
stlonp under Sleep Monitoring/Polysomnography/Sleep Architecture in CFS variables
Self-reported in-bed time on week nights, school nights, work nights or days, current shift - varies
sched_0901 under Sleep Questionnaires/Sleep Habits in STAGES variables
When working these hours, what time do you usually get into bed to sleep? It varies.
Self-reported in-bed time on week nights, school nights, work nights or days, next shift - varies
sched_1301 under Sleep Questionnaires/Sleep Habits in STAGES variables

sched_1701 under Sleep Questionnaires/Sleep Habits in STAGES variables
When working these hours, what time do you usually get into bed to sleep? It varies.
Self-reported in-bed time on weekend nights, non-school nights, non-work nights or days - varies
sched_1901 under Sleep Questionnaires/Sleep Habits in STAGES variables
On days you are not working, what time do you usually get into bed to sleep? It varies.
Average daily duration of rest period in weekdays from actigraphy
