how to include a timezone on a timetable in matlab

To include a timezone on a timetable in MATLAB, you can use datetime arrays. Here is an example:

main.m
% Create a datetime array with time zone information
time = datetime('now', 'TimeZone', 'America/New_York')

% Create a timetable with the datetime array as a column
TT = timetable(time)
187 chars
6 lines

In this example, time is a datetime array that includes the time zone information for New York. The timetable function is then used to create a timetable with time as one of its columns.

You can also add a time zone to an existing timetable by adding a column of datetime arrays with time zone information. For example:

main.m
% Create a timetable without a time zone
TT = timetable(rand(5,1), rand(5,1), rand(5,1));

% Add a column with time zone information
time = datetime('now', 'TimeZone', 'America/Los_Angeles');
TT.Timezone = repmat({time.TimeZone}, height(TT), 1);
TT.Time = datetime(TT.Time, 'TimeZone', TT.Timezone);
300 chars
8 lines

In this example, the Timezone property of the timetable is set to the time zone for Los Angeles. This property is then used to create a column of datetime arrays with the same time zone. Finally, the Time column of the timetable is converted to datetime arrays with the appropriate time zone using the datetime function.
