ans =

class structure(8).timetotemp
is like
class('structure(8).timetotemp')
which return char.
The correct function syntax call is
class(structure(8).timetotemp)

This code, class structure(8).timetotemp, is equivalent to:
class('structure(8).timetotemp')
If you had a variable array named structure whose 8th element had a property or field named timetotemp and you wanted to know the class of that property or field, use the function form of the class function call rather than the command form.
structure(8) = struct('timetotemp', datetime('today'))
class(structure(8).timetotemp)
