Drag and Drop Issue about svelte-gantt

[ANovokmet]

@labs20 Thank you, seems the tasks are rounded to the UTC date, instead of the local one. I am using your exact configuration, and when droppings tasks they last from 02:00-02:00 instead of 00:00-00:00. I issued a fix when using moment. It will need fixing for when using the default adapter, possibly leveraging Date.prototype.getTimezoneOffset.

I face one issue when drag and drop new task,
when week view selected and drop new task at last week day then new task not plot exact drop time (position) instead plot few hours early.

I can verify there is a bug here, thanks for reporting.

also plot working fine starting week days, when you drop new task incremental day then it plot few hours ago and increase plot hours.

Can you elaborate more? What do you mean by incremental day and plot here? Increase plot hours? Does the gantt date range get changed?

thanks @ANovokmet for quick reply

when week view selected and you drop new task week first day (SUN) then it looks drop and plot time all most same when drop new task week second day (Mon) then drop and plot time differ, when drop new task next day and continue the time different between drop and plot increase.

Thanks

only header hours display wrong, it show based on time zone.
I use moment.
dateAdapter: new MomentSvelteGanttDateAdapter(moment),

Thanks again @ANovokmet

[ANovokmet]

Which time zone are you in?

[nitish-darji]

IST (India Standard Time)

[ANovokmet]

Thanks, there are some issues with timezones since dropping moment. Will have to take them into account when calculating the hours.

[nitish-darji]

Hello @ANovokmet

Any update regarding time zones issue,

Thanks

[ANovokmet]

@nitish-darji sorry, working on it now

Can you describe your problem in details ? And which timezone ? Thanks

[labs20]

Hi. Thanks for your attention.

Timezone -3 (pt-BR)

In the example below, I've dragged a task that was set on the gant beggining at 2022-10-17 and ending at 2022-10-19.

I have:

                    columnUnit: 'day',
                    columnOffset: 1,
                    magnetUnit: 'day',
                    magnetOffset: 1,
                   ...

So at the gantt, the task seems to start at 00:00hs of 2022-10-17 until 23:59 of 2022-10-19.

But as I drag it one day back, to 2022-10-16, this is what I got:

this.gantt.api.tasks.on.changed(async ([ev]) => {

                // ev.task.model=> from: 1665964800000, to: 1666224000000
                // Cast do date:
                //  new Date(ev.task.model.from).toISOString()    => '2022-10-17T00:00:00.000Z'
                //  new Date(ev.task.model.from).toDateString()  => 'Sun Oct 16 2022' (timestamp here is '21:00:00 GMT-0300'
                // I've lost the timezone here

                // And look whats happening with model.to
                // Cast do date:
                //  new Date(ev.task.model.to).toISOString()    => '2022-10-20T00:00:00.000Z'
                //  new Date(ev.task.model.from).toDateString()  => 'Wed Oct 19 2022' (timestamp here is '21:00:00 GMT-0300'
            

                if (ev) {
                    let i = new Date(ev.task.model.from)
                        , f =new Date(ev.task.model.to)
                    ;

                    // Have to force things here
                    i.setHours(0, 0, 0);
                    f.setHours(23, 23, 59);
                    f.setDate(f.getDate() - 1);

                    this.data_to_server = {
                        id      : ev.task.model.id,
                        inicio  : i.toISOString(),
                        fim     : f.toISOString(),
                        to_id   : ev.sourceRow.model.id !== ev.targetRow.model.id ? ev.targetRow.model.id : undefined
                    };

                    this.touched = true;
                    this.force_event = true;
                    await this.checkCompEvents();
                    this.rodou_comp_event = false;
                }
            });

Hope the details help.
