For a date field, when more filters and sorting are in action, setting a time in a date field in a table or even in the tasks is impossible. It always resets to 12:00.
Also even if I set somehow the time, in different tables if I sort it - it resets automatically.
This make use of time field impossible.
Hello @martin.jokub, sorry for a delayed reply!
Are you still having this issue?
We have tested this a bit according to the information you wrote but unfortunately, we haven’t managed to reproduce the issue. Also, we haven’t heard similar complaints from other members so we could use a bit more information to look into this. 
If the issue persists on your end, would you be so kind as to reach out to our chat support so we can discuss this in a bit more detail? And if you have a few minutes to record a short video and send it to Boka in our chat support, we would greatly appreciate it.
Thank you!
The issue appeared also to me when I created a Gantt with “reversed timing”: from “Due date” to “start date”. It went crazy resetting all due time to 12:00 and giving me a “start date” before the “due date”. I bet that was the issue.
But I had a problem with time when exporting in CVS, it looks like it does it in a different time zone!
EDIT: I corrected the Gantt and changed back the time and all works fine now.
