converting time for different countries

So when the user inser the time,(otherwise the time is alreday set from the beginning as it's shown which is London for me)

how can I convert it into different countries time zone?

This is what i did and I got an error,

london= datetime(2019,02,28,0,0,0,'TimeZone','local','format','d - MMM - y HH:mm:ss Z')
for time =input('Choose: Amsterdam,Tokyo,Canberra,Los Angeles,New York,Local(London)')
if time == 'amsterdam' | 'Amsterdam'
ams= london +hours(1)
disp(ams)
elseif time == 'Tokyo' | 'tokyo'
tok= london + hours(9)
disp(tok)
elseif time == 'Canberra'|'canberra'
can = london +hours(11)
disp(can)
elseif time == 'Los Angeles'|'los angeles'
los= london + hours(-8)
disp(los)
elseif time == 'New York' |'new york'
new= london +hours(-5)
disp(new)
else
disp('Choose again')
end
end

As this was a part of my project at school, I am concerned if anyone would use my answer on their projects too.

Ella,

The volunteers respond for the good of everyone, including other students who might have similar questions.

Public responses that everyone can read is the price that we "charge" for our volunteer services: people who do not want responses to become public should be hiring private consultants.

I've marked it as homework for you. Because it's homework, just as others can't copy your answer, you can't submit my answer as your own either, or you might get in trouble.

Why make them type it in? Just use menu():

london= datetime(2019,02,28,0,0,0,'TimeZone','local','format','d - MMM - y HH:mm:ss Z')
timeZones = {'Amsterdam', 'Tokyo', 'Canberra', 'Los Angeles', 'New York', 'Local (London)'}
button = menu('Choose your time zone', timeZones)
if button == 1
	 % Amsterdam
	ams= london +hours(1)
	disp(ams)
elseif button == 2
	% Tokyo
	tok= london + hours(9)
	disp(tok)
elseif button == 3
	% Canberra
	can = london +hours(11)
	disp(can)
elseif button == 4
	% Los Angeles
	los= london + hours(-8)
	disp(los)
elseif button == 5
	% New York
	new = london + hours(-5)
	disp(new)
else
	% London
	disp('No time difference from London to London')
end

if strcmpi(time, 'Amsterdam')  %case insensitive comparisons
    ams = ...
    disp(ams)
elseif strcmpi(time, 'Tokyo')
     tok = ...
     disp(tok)
elseif ....
end

or

if ismember(time, {'amsterdam', 'Amsterdam'})
    ams = ...
    disp(ams)
elseif ismember(time, {'tokyo', 'Tokyo'})
    tok = ...
    disp(tok)
elseif ...
end
