A timetable holds several variables of different data types. You must specify which variable in your timetable you want to subtract from.
See this page on how to Access Data in Tables
% Create the timetable
MeasurementTime = datetime({'2015-12-18 08:03:05';'2015-12-18 10:03:17';'2015-12-18 12:03:13'});
Temp = [37.3;39.1;42.3];
Pressure = [30.1;30.03;29.9];
WindSpeed = [13.4;6.5;7.3];
TT = timetable(MeasurementTime,Temp,Pressure,WindSpeed)
% Subtract from a variable in timetable TT
TT.Temp - 5
% Your error - subtract from timetable TT
TT - 5
