DURATION_EXT is a 4-digit numeric variable reported in minutes.

Description

DURATION_EXT reports the duration of the activity in minutes. It is the same as DURATION, which truncates the final activity at 4:00 a.m., except for the last activity reported. The last activity of the diary day is not truncated at 4:00 a.m. As a result, the diary day may be longer than 24 hours.

This variable is available via extracts that are hierarchical or rectangular (activity) (more info on extract formats). If you request a hierarchical extract and plan to construct time use variables in your statistics package, this variable may be useful to you. If you request a rectangular extract and plan to construct time use variables through the extract system, DURATION_EXT will not be included in your extract, as persons are the unit of observation for rectangular extracts rather than activity or who records.
