Dear All,
I think it is hard to find out the absolute date (current date). Because the computer date can be changed, for example, today is June 09, 2020, if I run datetime, it could find June 09, 2020. But if I change my computer date to 09 May 2020, datetime will give me 09 May 2020 which is Not the correct date of today. Is there a way to solve this problem?
Thanks a lot.

A simple search showed several possible solutions.
s1 = webread('');
s2 = regexp(s1, '<BR>(.*)\sUTC','tokens','once');
t = datetime(s2,'InputFormat','MMM. dd, HH:mm:ss');

Hi, David,
Thanks for your help. I run your code and got the followinf error message:
Error using webread (line 122)
The connection to URL '' timed out after 5.000 seconds. The reason is "Connection timed out after
5103 milliseconds". Perhaps the server is not responding or weboptions.Timeout needs to be set to a higher value.
Error in MainSEGNDSE01 (line 20)
s1 = webread('');
