Incorrect calculation of task duration based on subtask duration

[VR Hetrick]

Because of client preference, I normally run my date
settings as yyyy-dd-mm on the system they've assigned to
me for on-site work. Thursday, I was working with Project
2000 and found that, for a two-project that had the
correct duration information in all the subtasks, the
tasks had incorrect duration information. One task that
should have totalled 3 days was listed at 34.79 days and
the following task was listed at 78.16 days.

On the suspicion that the problem was with the system
date, I changed the system date back to mm-dd-yyyy and,
voila, all the task durations magically were corrected.

My question is whether anybody knows of a fix for this
particular problem? I didn't find anything by searching
on "incorrect calculation task duration" or "task duration
incorrectly calculated".

Thanks for any light anybody can shed.

I've never heard of this. Try a couple of other date formats such as mmm d
yyyy and let us know if it's only the one format that causes problems.

Does the problem also occur in a new project you create with one summary and
say two sub tasks? If it is that repeatable then a fix could be found, but
not immediately.

For now I think this date format shouldn't be used.

Out of interest, what region and language, for example is it for US English
and US region in Windows?
