Matlab is mixing MONTH and DAY up

7 views (last 30 days)
Hello, I have a datetime array where the format is dd/MM/yyyy, but when I used ymd(), Matlab tells me that day is month and month is day. Using format() just rearranges the date but retains the confusion between day and month.
How do I rectify this, how can I dictate to Matlab which is the month and which is the day?
y =
m =
9 %this is actually the day
d = %this is actually the month

I think I need to specify the format of the LOCALDATE data as I read it in but not sure how to do that.

Try this:
D = load('gps.mat');
gps = D.gps;
LOCALDATETIME = datetime(string(gps.LOCALDATE),'InputFormat','dd/MM/yyyy', 'Format','dd/MM/yyyy HH:mm:ss') + gps.LOCALTIME;
First_5_Rows = LOCALDATETIME(1:5)
First_5_Rows =
5×1 datetime array

09/03/2021 08:42:32
09/03/2021 08:42:34
09/03/2021 08:42:35
09/03/2021 08:42:36
Since ‘gps.LOCALDATE’ is already a datetime array, converting it first to a string variable allowed datetime to parse it correctly.
