Just for the record, David was correct, except for one subtle point: the row times in a timetable are metadata, not one of the variables. You can access them by name in exactly the same way, though.
David created his timetable with a workspace variable named MeasurementTime, whose name the timetable picked up; that's why his row times were named Measurement time. The default name is Time, though.

variant
a = rand(20,6);
date1 = datetime(2019,4,19) + hours(cumsum(70*rand(20,1)));
TT = array2timetable(a,'RowTimes',date1);
date_out = TT.Time;

You can also use directly:
TT = timetable(Temp,Pressure,WindSpeed,WindDirection, 'RowTimes',MeasurementTime)
datetime_vec = TT.Time
