Dates on the Gantt chart don't align with durations

[grantman1]

Hi,
I have tried to replicate your scenario. But the duration is working fine can you please make these steps again with recording so I can have more information on why it is not working correctly in your scenario?

Or Could the error I am having now be due this sitting?

Please see the screenshot below.

Hello, I have attached the video below.

Hi, We have verified the issues. It is most probably because of the Start/End Date in the past. Moreover, I have created this issue on github and will fix this ASAP. You can check the issue on github by following this link: https://github.com/bryntum/odoo-support/issues/125#issue-1890102468

Hello, I just did this test and it is still incorrect even when the time is the future. please see the attachment below.

Hello,
I've checked the provided video and it looks like the project has hoursPerDays config set to 24. Doing this means that 1 day unit equals 24 hours.
So the task duration is 5 days = 5 * 24 = 120 hours.
But the project calendar allows to work for 8 hours/day only.
That's why the task lasts for three weeks.

So to sum up the solutions are either:

1. change the project to use a 24 hours/day calendar (like general calendar from your screenshot)
2. change the project hoursPerDay value to 8.

Hello arcady

I have tried it and it worked when i changed the calendar to general. Please do you know how can i set the entire project calendar to general? so it can all display correctly. Option (1) i mean.

It's just meant to be part of the data you load into the Gantt. I don't know how it's done in Odoo but this is for example how loaded data look in our demos (I just replaced real data with ... to reduce its size):

{
  "success" : true,
  "project" : {
    "calendar"     : "general",
    "startDate"    : "2019-01-14",
    "hoursPerDay"  : 24,
    "daysPerWeek"  : 5,
    "daysPerMonth" : 20
  },
  "calendars" : {
    "rows" : [
      ...
    ]
  },
  "tasks" : {
    "rows" : [...]
  },
  "dependencies" : {
    "rows" : [...]
  },
  "resources" : {
    "rows" : [...]
  },
  "assignments" : {
    "rows" : [...]
  }
}

As you can see the data just has project property with the project field values including calendar.
