Nope.

When the hours of the tasks didn't add up with the daily attendance you had to tweak your data or you couldn't close the day. Either added or removed 1 minute to the work day.

So a work day with 8 hours maybe had 7.98 hours of tasks. You tweak around a bit so that they both matched.

This was a reported bug (incl. explanation from a programmer) that wasn't fixed for a very long time. Maybe it's still broken.
