Datetimes don't seem to be recognised

2 views (last 30 days)
Can anyone explain to me why this isn't working? For some reason, the datetime t is not recognised as occurring between times.t1.start and times.t1.end, even though it DOES! It is recognised as occurring after t1.start, but not before t1.end.
isbetween() also does not work so I am guessing I have overlooked something simple...
start=datetime(2021,08,11,09,58,25);
last=datetime(2021,08,11,10,01,00);
t=gps.DateTime(ii) %reading same datetime from my table
t=datetime(2021,08,11,09,59,25)
%if vessel position time occurs during particular transect working on
if (t>=start)&&(t<last)
%append it to specific part of structure
disp('It works!')
else
disp('It does not work')
end
%Datetime from my table:
t =
datetime
11-Aug-2021 09:59:25
%Datetime datetime(2021,08,11,09,59,25)
t =
datetime
11-Aug-2021 09:59:25

I’m not certain what you’re doing and I can’t run the posted code. I’m also not certain what the actual problem is.
See if the isbetween function will do what you want with respect to the if block.

If that doesn't work, perhaps the data in the file was more precise than you thought it was.
t1 = datetime(2021, 11, 10, 14, 25, 00)
t1 = datetime
10-Nov-2021 14:25:00
t2 = datetime(2021, 11, 10, 14, 25, 0.4)
t2 = datetime
10-Nov-2021 14:25:00
t1 >= t2 % correctly false even though they display the same
ans = logical
