Effort per Day: mismatch between total and sum of efforts

In the effort viewer in "Effort per Day" mode (no rounding), I observe that there is frequently a mismatch
between the displayed daily total and the actual sum of efforts of that day.

E.g.:
Total = 3:57:16, but efforts = 3:36:54 + 0:03:05, or
Total = 1:21:05, but efforts = 0:41:39 + 0:10:30 + 0:23:48 = 1:15:57, or
Total = 2:05:13, but single effort = 0:58:23, or
Total = 8:05:13, but sum of efforts = 6:24:34

At least in the last of these examples, I have verified that it is the total which is correct, and the
individual efforts are wrong. (Calculated the total myself here, but could attach a screenshot to prove it.)

I am experiencing this in TaskCoach 1.3.16 and can't remember having seen that frightening behaviour in
earlier versions of it.

Is there a simple explanation to it? Or should I open a bug report and add an anonymized *.tsk file?

Yves

How are they wrong ? I think it's because of a rounding error; times are stored with a better than 1s precision
but are displayed rounded to the second.

Hi Jérôme,

thanks for responding.

Unfortunately this is not about rounding errors in the range of seconds. Please follow up with the bug
report I have created:

https://sourceforge.net/tracker/?func=detail&aid=3537707&group_id=130831&atid=719135

Ah, thanks for the report. I'll take a look at that ASAP.

There have been lots of changes in this area to work around the slow
pubsub subscribe method that you fixed recently. So maybe it's
possible to undo my changes. I'll take a look.

I committed a fix to our source code repository that you test via
http://taskcoach.org/download_daily_build.html.

I expect to release a new version of Task Coach next weekend.
