Converting unix time to real time

I want to convert Unix Time Stamp like this '1641031963.398125' in a Format like this "Friday, 21. December 2018 11:14:24.126".

I used: date_time = datestr(unix_time/86400 + datenum(1970,1,1));

but the answer is a char vector which is not the correct time:

how can I convert unix to real time? any help will be appreciated.

Answer 1

[Walter Roberson]

datetime(1641031963.398125, 'ConvertFrom', 'posixtime', 'Format', 'eeee, d. MMMM uuuu H:mm:ss.SSS')

ans = datetime
   Saturday, 1. January 2022 10:12:43.398

It was not completely clear whether you wanted leading zeros on the hour or not.

I suspect you forgot to convert the char to a value:

unix_time='1641031963.398125';
unix_time=str2double(unix_time);
date_time = datestr(unix_time/86400 + datenum(1970,1,1))

date_time = '01-Jan-2022 10:12:43'
