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, START will not be included in your extract, as persons are the unit of observation for rectangular extracts rather than activity or who records.
