Ronald,



Is it possible that P5 is just rounding up the finish of 08:59.99999999 to coincide with our understanding that, for all practical purposes, it is 09:00 – albeit for an infinitesimally short period?

Guys

I am an Oil project planner, so 1 minute is not important in my job and also I usually choose day as unit date instead of hour :)

But here should be a reason that why primavera starts described activity on 8:01 am instead of 8:00

Dear Ronald

In a sample project define an activity with 1 hr duration and consider its start date as 8:00 am, you will find that program calculate finish date as 9:00 am not 8:59 am

You will get a great response from Primavera on this one.

All about 24 hr calendars v 5*8 hr calendars, the hours option switched on or off, activities finishing or not finishing at 00.00, and scheduling to data dates without specifying yje hour of day etc.

It obviously only makes sense to the software programmers!!

Amir,



P5 starts work at the beginning of the minute and finishes work at the end of the minute. If an activity started at 8:00 am and finished at 9:00 am, then that would constitute a total of 61 minutes! To get 60 minutes in an hour, work has to start at 8:01 am and finish at 9:00 am. Good luck!

we know. This has been an "issue" since version 3.0. I HATE sf relationships, can’t you use the zero free float constraint with FS instead?
