XTIMEWT is a 16-digit numeric variable.
XTIMEWT is the RECWGHT, limited to states in all samples
The 1992-1994 and the 2003 forward surveys sampled all contiguous states, and since 2003 onward, ATUS additionally included Hawaii and Alaska in the sample. The earlier surveys did not cover some of the smaller and more rural states nor did they include Hawaii and Alaska. As there is some possibility that these differences in the sample base may affect some result, XTIMEWT was used as an additional weight. This cross-time weight is the same as the RECWGHT, for the 1965-1966, 1975-1976 and 1985 surveys. But exclude the diarists from the additional states in 1992-1994 and 2003 forward.
