repeated measures anova using time (date format) variable

[msherman]

Dear List: I have a time (4 time values for four decision points)  variable (e.g. 08:45:55) in which I have conducted a repeated measures anova. The descriptive statistics that are printed provide the mean time for each decision point and SDs. When I look at the  estimated means the values that are printed out are like: 31714.167. I am not clear as to what this value actually means. Any ideas? thanks,  martin sherman

This is the underlying numeric measured in seconds. You probably have to
activate the table and set the format in the cell to the time format to see
it as a time.

SPSS time values are in seconds since midnight. 31714.167 is 8.8095
hours (dividing by 3600), or 8:48:34 in the morning
