Add time zone support to TimelineHistogram

[JockeLindberg]

Forum post

Hi all,

We would like to utilise timeline histogram component (https://www.bryntum.com/products/scheduler/examples/timelinehistogram/) and display it next to scheduler.

I would like to display the same date ranges both in scheduler and timeline histogram.

I noticed that timeline-histogram has timeZone property but does not convert start/end date to configured timezone.

The workaround is to maintain different start/end date value for scheduler and timeline histogram but would be nice if the components behave the same.

Example:

My computer tz: UTC+1;

timeZoneIana = 'UTC';
schedulerStartDateTime = '2024-01-22T08:00:00.000Z';
schedulerEndDateTime = '2024-01-26T23:59:59.999Z';
I would expect that both scheduler and timeline histogram display: 22.01.2024 08:00 start and 26.01.2024 23:59:59 end.

Unfortunately timeline-histogram display my computer timezone.

Please see demo project in the attachment.

Best regards,
Kornel
