Synchronize Timetables
The timetables, indoors and outdoors, contain different measurements taken inside
and outside a building at different times. Combine all the data into one timetable with the
synchronize function.
tt = synchronize(indoors,outdoors);

The output timetable, tt contains all the times from both timetables. synchronize puts
a missing data indicator where there are no data values to place in tt. When both input
timetables have a variable with the same name, such as Humidity, synchronize
renames both variables and adds both to the output timetable.
