1. What is the problem? Be very detailed.
Start and End times are in the correct format, and excel can easily change them to Date,Time+Timezone format.
But the submission times are always in GMT and Excel is not able to change it because they are in a different format.
2. What app or server are you using and on what device and operating system? Include version numbers.
3. What you have you tried to fix the problem?
I can add the timezone manually to GMT to get the correct time, but it's a workaround to a bug.
4. What steps can we take to reproduce the problem?
Make any submission and check the excel file.
Start and End times are written like this: 2019-11-21T10:32:27.405+04:00
Submission times are written like this: 2019-11-21T15:23:05
