How Papershift rounds time tracking

In the user interface of our apps and in the web application, tracked times are displayed in the format HH:MM (e.g. 07:00). In our database, however, the times are stored and calculated to the second.

This can lead to the following cases, which at first glance give the impression that there is an error:
If an employee starts a time tracking at 07:00:12 and ends it at 15:00:58 in the time tracking overview it will create a time tracking from 07:00 - 15:00 which corresponds to a total length of 8 hours. However, the actual length of the time tracking is 8 hours and 46 seconds and is therefore displayed by us as 8.01 h. 

The tracked working times are stored in our database to the second and are calculated correctly at the end in the record.
