Maybe you don't know it yet: in Redmine you can not only log spent and estimated time in hours but also in minutes.
Yes, although you will see the field “Hours…” on the log time form, time logging can be entered using different formats.
This is the “Log time” form”:
In “Hours” field, you can log time with the following formats:
- Hours and minutes using standard time format:
- Hours and minutes using decimal time format:
You have to take into account that logged time will always display in decimal time format. That means: if you log 2h20m, Redmine will display 2.33 hours.
All these comments are valid also for “estimated time” field.
I hope this was a useful tip for you!
