It is not a time value, it is a TimeSpan - read it as the Time Spanned (Time Passed if you wish).

You can add a TS value to any date, and yes any time in that day would be less than that. ie:

var myDate = new DateTime(2018,1,1);

var startOfNextDay = myDate + TimeSpan.FromHours(24);

var anyTimeInMyDate = new DateTime(2018, 1, 1, HH, MM, SS, MS);

anyTimeInMyDate is before startOfNextDay. IOW:

anyTimeInMyDate.Date.AddDays(1) is equal to startOfNextDay.
