Description

Description¶

We use Redmine version 6.0.3.stable and a custom script to synchronize time entries from toggl to Redmine.
This worked well so far but after the update to 6.0.3.stable we noticed that some time entries have incorrect values for hours.
Example: we are creating a new time entry and send "hours: 0.44". The resulting time entry has the value "0.43" for property "hours".

Is there any sanitizing or rounding of values in Redmine weare unaware of? It worked in Redmine 5 so there has to be some changes.

Environment¶

I've tested creating the time entry using postman and got the same result (see attached video). Creating a time entry with <hours>0.44</hours> results in a new item with <hours>0.43</hours>.
Using other values works.

Category changed from REST API to Time tracking

Since Redmine 6.0.0, decimal values entered in the "Spent time" field are rounded to the nearest minute. For example, 0.44 hours (26 minutes and 24 seconds) is rounded to 26 minutes and stored in the database as 0.43333333333333335. When displayed on the screen, it is shown with two decimal places as 0.43.

This change was made in #40914 to prevent calculation errors in spent time.
